1.1. ANSYS 9.0 New Features and Enhancements
1.1.1. Installation and Licensing Changes
The following features have been added or updated at ANSYS 9.0. Unless otherwise noted, all items listed below
apply to both Windows and UNIX platforms.
The ANSLIC_ADMIN utility has been redesigned for better ease-of-use and consistency across Windows and
UNIX platforms. For more information on the ANSLIC_ADMIN utility, see the ANSYS, Inc. Licensing Guide.
License borrowing is now available, allowing an ANSYS user at your site to use the product outside of your
companyfacility(sothatanengineercantakealicensehomeonanotebookcomputer,forexample).Touselicense
borrowing, you must have license keys that specify borrowable licenses. A new borrowing utility, accessible from
the ANSLIC_ADMIN utility, allows you to select the license(s) you want to borrow, specify the amount of time
for which you want to borrow them, and to return borrowed licenses early. License borrowing is available only
on Windows platforms. For more information, see Section 5.6: Using License Borrowing in the ANSYS,Inc.Licensing
Guide.
The ANSYS Launcher now allows you to launch Distributed ANSYS or the distributed solvers in shared-memory
ANSYS. Using the Solver Setup tab, you can specify the type of MPI to use and either the number of processors
on a local machine or the hosts to use for multiple machines. For more information about setting up a distributed
environment, see the Distributed ANSYS Guide or the Installation and Configuration Guide for your platform.
ANSYS Release Notes . ANSYS Release 9.0 . KS278-RN . © SAS IP, Inc.

TheANSYSandWorkbenchproductinstallationsarenowmoreconsistentbetweenproductsandacrossplatforms.
On UNIX installations for both ANSYS and Workbench, the option to use the symbolic link is available earlier in
the installation, at the point where you specify your mount and installation directories. At Release 9.0, the sym-
bolic link option is on by default.
ANSYS now supports the 64-bit Fujitsu SPARC64 IV platform running Solaris 8 and the AMD Opteron 64-bit Linux
platform running SuSE SLES 8.
ANSYS now supports native 64-bit versions of Parasolid and SAT Connections and LS-DYNA (previous releases
used a 32-bit version).
1.1.2. Structural
ANSYS 9.0 includes the following new features and enhancements that expand your ability to perform structural
analyses.
1.1.2.1. Contact
The following new features expand your ability to perform structural analyses involving contact.
1.1.2.1.1. Mesh-Independent Spot Weld
The new spot weld feature allows you to easily model thin sheet components that are connected with spot
welds, rivets, or fasteners. This feature is based on the multipoint constraint (MPC) contact approach. The spot
weld can be located anywhere between the parts that are to be connected, independent of the mesh and the
node locations. Each spot weld set connects two or more surfaces.
Advantages to using the mesh-independent spot weld capability are:
• You can mesh parts independently.
• The program takes into account effects of the spot weld radius that you input.
• You can use rigid or deformable beams to model each spot weld set. In addition, beam forces, moments,
and stresses for each spot weld set are available during postprocessing.
Four new commands are available to create and manage spot welds. Use the SWGEN command to create a new
spot weld set, the SWADD command to add more surfaces to an existing spot weld set, and SWLIST and SWDEL
to list and delete spot welds, respectively. For more information on the spot weld feature, see Chapter 8, “ Spot
Welds” in the ANSYS Contact Technology Guide.
1.1.2.1.2. Penalty-Based Shell-Shell Assemblies
Typically, you would use bonded contact with the multipoint constraint (MPC) approach to model shell-shell
assemblies. However, in cases where the MPC approach causes the model to be overconstrained, you can use
the new penalty-based shell-shell assembly feature instead. This method uses penalty stiffness to constrain ro-
tational degrees of freedom in addition to translational degrees of freedom. The new capability is available for
contact elements CONTA173, CONTA174, and CONTA175 when used with TARGE170. See Section 3.8.11.3:
Bonded Contact for Shell-Shell Assemblies in the ANSYS Contact Technology Guide for more information.
1.1.2.1.3. MPC Approach Supports No-Separation Contact
You can now use the no-separation option (KEYOPT(12) = 4 on the contact element) with the MPC approach to
model solid-solid assemblies that represent a slider line (2-D) or slider plane (3-D). This capability is available for

contactelementsCONTA171throughCONTA175.SeeSection7.1:ModelingSolid-SolidandShell-ShellAssemblies
in the ANSYS Contact Technology Guide for more information.
1.1.2.1.4. Revised Contact Algorithm KEYOPT for CONTA178
KEYOPT(2)oftheCONTA178node-to-nodecontactelementcontrolswhichcontactalgorithmisused.Theoptions
for KEYOPT(2) have been reordered to be consistent with the surface-to-surface and node-to-surface contact
elements (CONTA171 through CONTA175). As a result, the new default contact algorithm for this element is the
augmented Lagrange method. The new format of KEYOPT(2) is:
KEYOPT(2)
Contact Algorithm:
0 - Augmented Lagrange method (default)
1 - Pure penalty method
3 - Lagrange multiplier on contact normal and penalty on tangent (uses u-P formulation for normal contact,
non-u-P formulation for tangential contact)
4 - Lagrange multiplier method
1.1.2.1.5. Tracking Contact During Solution
An enhancement to the NLDIAG command allows you to monitor contact diagnostic information for all defined
contactpairsduringthesolution.TheinformationiswrittentoatextfilenamedJobname.cndatauser-specified
frequency (each iteration, substep, or load step). Using this information, you can identify when and how contact
occurs, determine the regions where contact is unstable, and identify the corresponding contact parameters.
You can then focus on the specific settings for those particular contact pairs that need attention. See the docu-
mentation for the NLDIAG command for more information.
1.1.2.1.6. Recovering Contact Default Settings
A new CNCHECK command option allows you to reset all real constant and KEYOPT values back to their default
settings for specified contact pairs. The new feature provides a convenient way to reset the values after contact
pairs have been defined. See the documentation for the CNCHECK command for details.
1.1.2.1.7. New Documentation: ANSYS Contact Technology Guide
Documentation for the ANSYS contact capabilities has been moved from the ANSYS Structural Analysis Guide to
a new ANSYSContactTechnologyGuide. The large (and ever increasing) amount of contact information previously
contained in one chapter is now broken into several chapters within the new guide, making it easier to read and
comprehend. The new guide also presents the information in a more logical sequence.
1.1.2.2. Element Technology
The following element technology enhancements are available in this ANSYS release:
1.1.2.2.1. Manual Rezoning
Inafinitelarge-deformationanalysis,meshdistortionreducessimulationaccuracy,causesconvergencedifficulties,
and can eventually terminate an analysis. Rezoning allows you to repair the distorted mesh and continue the
simulation. Manual rezoning means that you decide when to use rezoning and what region to rezone; then, you
generate a new mesh on the selected region. During the rezoning process, ANSYS updates the database as ne-
cessary, generates contact elements if needed, transfers boundary conditions and loads from the original mesh,
and maps all solved variables (node and element solutions) to the new mesh automatically. Afterwards, with

Section 1.1: ANSYS 9.0 New Features and Enhancements

equilibrium achieved based on the mapped variables, you can continue solving using the new mesh. For more
information, see Chapter 6, “Manual Rezoning” in the ANSYS Advanced Analysis Techniques Guide.
1.1.2.2.2. New Solid-Shell Element
SOLSH190 is a new 3-D solid-shell element that supports large strain analyses with a wide array of nonlinear
materials. The element has only translational degrees of freedom and eight-node brick connectivity.
The new element eliminates the problem of transitioning from solid to shell elements. The element allows for
modeling tapered shell sections without the need for midplane extraction. It performs well in simulating shell
structures with a wide range of thicknesses (from extremely thin to moderately thick). You can use it for both
flat plate and curved shell models. SOLSH190 is based directly on 3-D material laws--that is, no plane stress re-
duction is required--and automatically accounts for thickness change. Like other continuum elements, it supports
contact with exterior surfaces.
1.1.2.2.3. Follower Loads
A new one-node 3-D element named FOLLW201 is now available. You can overlay the element onto an existing
node with physical rotation degrees of freedom. The element specifies external forces and moments which follow
the deformation of a structure in a nonlinear analysis. FOLLW201 contributes follower load stiffness terms in a
geometrically nonlinear analysis (NLGEOM,ON). For more information, see the documentation for the FOLLW201
element.
1.1.2.2.4. Preintegrated General Shell Sections
You can now define homogenous shell section behavior directly via preintegrated general shell sections, a
methodcommonlyusedinanalysesinvolvinglaminatedcompositestructures.Withpreintegratedshellsections
(SECTYPE,,GENS), you can directly specify the membrane, bending, and coupling properties. The preintegrated
method also allows analysis of complex geometry (with repeated patterns such as corrugated sheets) using
equivalent shell section properties.
You can use preintegrated shell sections when linear elastic material behavior is acceptable. Compared to
standard shell usage with independent material and section definitions, preintegration requires minimal system
resources because numerical integration through the thickness of the shell is unnecessary. A series of new ANSYS
commands allows you to specify the particular component quantities necessary for defining a preintegrated
shell section. You can define each quantity of the preintegrated shell section data as temperature-dependent.
The preintegrated form of input allows you to import homogenous section-stiffness constants evaluated in
other analyses or by third-party, special-purpose software tools.
For more information, see Section 16.4: Using Preintegrated General Shell Sections in the ANSYS Structural Ana-
lysis Guide.
1.1.2.2.5. Nonlinear General Beam Sections
A nonlinear general beam section (SECTYPE,,GENB) is an abstract cross section type that allows you to directly
input the relationships of generalized stresses to generalized strains. You can define axial, flexural, torsional, and
transverse shear behavior as a function of axial strain, bending curvature, twist, and transverse shear strains.
Thegeneralizedsectionformofinputdoesnotrequirecrosssectiongeometrydataormaterialdataindependently.
For purposes of evaluating mass matrices, ANSYS assumes a unit area of cross section. This form of data is useful
forincludinganexperimentallymeasurednonlinearresponseofabeam-likestructuralcomponent,suchascross
section distortion not permitted when using normal beam sections.

Nonlineargeneralbeamsectionsalsoallowanonlinearrelationshipoftransverseshearforcestothecorresponding
transverse shear strains. Often, the input of generalized beam sections consists of the results of a prior detailed
slice analysis (for example, a segment of pipe analyzed using generalized plane strain elements).
For more information, see Section 15.5: Using Nonlinear General Beam Sections in the ANSYS Structural Analysis
Guide.
1.1.2.3. Linear Dynamics
The following enhancements are available in the area of linear dynamics:
1.1.2.3.1. Component Mode Synthesis (CMS)
The following CMS enhancements are available in this ANSYS release:
Offsetting a substructure at a different location When creating a new superelement from an existing one
(via a SESYMM or SETRAN command), you can now specify an offset value to the node or element IDs in the FE
geometry record. After performing the use and expansion passes for all CMS superelements, the mode shape
display of the entire assembled structure shows the offset superelements in their transformed locations. For
more information, see the documentation for the RSTOFF and SEEXP commands.
CMS Wizard A wizard is available to guide you through the CMS generation, use, and expansion passes. The
wizard also provides support for organizing and managing the files generated by a CMS analysis. You can access
the wizard in the ANSYS GUI via the Solution (/SOLU) menu.
1.1.2.3.2. Translational Acceleration of Element Components
ItisnowpossibletospecifythetranslationalaccelerationofanelementcomponentineachoftheglobalCartesian
(X, Y, and Z) axis directions. Using the new CMACEL command, you can specify translational, acceleration-based
loading on up to 100 element components. A typical use of the new capability involves applying acceleration
to the base of a structure to simulate ground acceleration in an earthquake.
Components for which you want to specify acceleration loading must consist of elements only. The elements
you use cannot be part of more than one component, and elements that share nodes cannot exist in different
element components. You cannot apply the loading to an assembly of element components.
You can define linear translational acceleration for the following analyses types:
• Static (ANTYPE,STATIC)
• Harmonic (ANTYPE,HARMIC), full or mode superposition method
• Transient (ANTYPE,TRANS), full or mode superposition method
• Substructure (ANTYPE,SUBSTR)
1.1.2.3.3. QR Damped Complex Eigensolver
Because unsymmetrical stiffness contributions can result from nonconservative friction forces between two
contact surfaces, the QR damped mode-extraction method has been extended to account for unsymmetrical
stiffness matrices. The unsymmetrical stiffness contributions of the original stiffness matrix are projected onto
the modal subspace and the reduced unsymmetrical eigenproblem is solved. The QR damped eigensolver is
faster and requires fewer computational resources than the existing damped or unsymmetrical eigensolvers.
The QR damped eigensolver now computes to complex eigenvectors of the quadratic eigenproblem. An inverse
iteration method calculates the complex eigenvectors in modal subspace. As a result, complex eigenvectors

fromtheoriginalsystemarerecoveredviathemodaltransformation.TheMODOPTcommand'sCPXMODoption
activates complex eigenmode extraction.
The QR damped eigensolver is also supported for partial solutions (PSOLVE), allowing a prestressed modal
analysis (PSTRES,ON) following a large deformation (NLGEOM,ON) static solution. Issuing a PSOLVE,EIGQRDA
command performs a QR damped eigensolution when an unsymmetrical stiffness matrix must be used in a
modal analysis. The new capability is useful in applications such as brake friction modeling through contact
elements (CONTA174) with the Newton-Raphson option set to unsymmetric (NROPT,UNSYM).
For more information, see the MODOPT command description, the PSOLVE command description, and Sec-
tion 3.13.7: QR Damped Method in the ANSYS Structural Analysis Guide.
1.1.2.4. Materials
The following materials enhancements are available in ANSYS 9.0:
1.1.2.4.1. Cast Iron Plasticity
The cast iron plasticity material model is more robust, accurate, and better performing. The new implementation
supports plane strain, axisymmetric, and 3-D stress states. (The plane stress and beam stress states are not sup-
ported.) The improved cast iron plasticity material model supports these elements: PLANE182, PLANE183, SOL-
ID185, SOLID186, and SOLID187.
1.1.2.4.2. Plasticity with Stress vs. Plastic Strain Data Input
You can now directly define the plastic strain vs. stress as stress-strain input data for plastic hardening behavior,
eliminating the duplicated Young’s modulus definition for material when using stress vs. total strain data (such
as MISO and KINH tables). Support is available for both multilinear isotropic (MISO) and kinematic hardening
(KINH). You can combine the new option with other ANSYS material models that currently support MISO and
KINH.
1.1.2.4.3. Frequency-Dependent Full Harmonic-Response Analysis
You can now perform a frequency-dependent, full harmonic-response analysis (ANTYPE, HARM) with a material
elastic property (TB,ELASTIC) and/or structural damping coefficient (TB,SDAMP). Issue the TBFIELD command
tospecifyafrequency-dependentpropertydatatable.Youcandefineseveralmaterialswithdifferentfrequency-
dependent behaviors and assign them to different parts of components. The new capability is available for ele-
ments PLANE182, PLANE183, SOLID185, SOLID186, and SOLID187.
1.1.2.5. Curve Fitting
Temperature-dependent curve fitting using individually specified temperatures is now available for all three
disciplines supported for material curve fitting (viscoelasticity, hyperelasticity, and creep). ANSYS curve-fitting
tools can now perform curve fitting at each given temperature, plotting curves of your experimental input data
withcurve-fitteddataandwritingthecorrespondingdata(TBDATA)withtemperatures(TBTEMP)tothedatabase.
For more information, see Chapter 9, “Material Curve Fitting” in the ANSYS Structural Analysis Guide.
1.1.3. Coupled-Field
ANSYS 9.0 includes the following enhancements that expand your ability to perform coupled-field analyses.

1.1.3.1. Thermal-Electric Analyses
A thermal-electric analysis capability is now available that accounts for Seebeck, Peltier, and Thomson thermo-
electric effects in addition to Joule heating. PLANE223, SOLID226, and SOLID227 now support this capability. To
include the Seebeck-Peltier thermoelectric effects, a Seebeck coefficient must be specified (MP,SBKX or SBKY or
SBKZ).TocapturetheThomsoneffect,thetemperaturedependenceoftheSeebeckcoefficientmustbespecified
(MPDATA,SBKX or SBKY or SBKZ). Typical applications include heating coils, fuses, thermocouples, and thermo-
electric coolers and generators.
A transient analysis using PLANE223, SOLID226, or SOLID227 can now account for both transient thermal and
transient electrical effects.
For more information, see Thermal-Electric Analysis in the ANSYS Coupled-Field Analysis Guide.
1.1.4. Low-Frequency Electromagnetics
ANSYS9.0includesthefollowingnewfeaturesandenhancementsintheareaoflow-frequencyelectromagnetics.
1.1.4.1. Extracting Conductance
A GMATRIX macro is now available to extract conductance from multi-conductor systems. This macro, which is
used much like the CMATRIX macro for capacitance, allows you to extract self and mutual conductance terms
so that equivalent circuit lumped conductors can be defined for use in circuit simulators.
GMATRIXworkswiththefollowingelements:SOLID5,PLANE67,LINK68,SOLID69,SOLID98,PLANE230,SOLID231,
and SOLID232.
For more information, see the GMATRIX command description in the ANSYS Commands Reference and the dis-
cussion in the Electric Field Analysis chapter of the ANSYS Low-Frequency Electromagnetic Analysis Guide.
1.1.4.2. Electromagnetic Force and Torque
Use the new EMFT command to summarize electromagnetic force and torque on a selected set of nodes. The
EMFTcommandworksonanysetofselectednodes,notjustbodies.Inaddition,theEMFTcommandincorporates
both Lorentz and reluctance forces, with no need to differentiate between Maxwell, virtual work, and Lorentz
forces. It is applicable to both surface and body forces.
Unlike FMAGSUM, which requires you to specify element components first and then flag them using FMAGBC,
EMFT requires only that you select the nodes of interest and issue the EMFT command. In addition, the under-
lying stress pass evaluation time during solution will be notably faster (up to three times faster).
This command is available only for static analyses using SOLID117, PLANE121, SOLID122, or SOLID123 elements.
For all other analysis, continue to use the FMAGSUM procedure.
For more information on using EMFT, see the description in the ANSYS Commands Reference, the discussion on
calculating magnetic force and torque for a static edge-based analysis in ANSYS Low-Frequency Electromagnetic
Analysis Guide, and the discussion on electromagnetic forces in an electrostatic field analysis, also in the ANSYS
Low-Frequency Electromagnetic Analysis Guide
1.1.5. High-Frequency Electromagnetics
ANSYS9.0includesthefollowingnewfeaturesandenhancementsintheareaofhigh-frequencyelectromagnetics.

1.1.5.1. Scattering Analysis of Periodic Structures
A plane wave source port is now available to launch a plane wave for a scattering analysis of a periodic structure
(Frequency Selective Surface) (via HFPORT). Radar cross section results can be displayed and printed for 2-D TE
and TM incident plane waves (via PLHFFAR and PRHFFAR). Reflection and transmission properties of frequency
selective surfaces can now be calculated using the new FSSPARM command macro. For more information, see
Applying Excitation Sources in the ANSYS High-Frequency Electromagnetic Analysis Guide.
1.1.5.2. Lumped Circuits
Lumped circuits are now available to simplify your high-frequency analysis. You apply them to the mid-nodes
ofelementedgesusingtheBFcommand.Formoreinformation,seeLumpedCircuitsintheANSYSHigh-Frequency
Electromagnetic Analysis Guide.
1.1.5.3. Fast Frequency Sweep Performance
A Variational Technology method using a perfect absorber is now available for S-parameter calculations over a
frequency range (via SPSWP or HROPT). It provides about a 20% faster solution than the original Variational
Technology method. For more information, see ANSYS Frequency Sweep VT in the ANSYS Advanced Analysis
Techniques Guide.
1.1.5.4. Port Enhancements
Power terms of multi-port networks can now be calculated using the new HFPOWER command macro.

Results are stored in the HF119 and HF120 Item and Sequence Numbers Table.
1.1.5.6. Smith Chart and Network Parameter Conversion
You can now plot scattering, admittance, or impedance parameters on a Smith chart. The new PLSCH command
converts any input parameter type to a specified output parameter type and plots the results on a Smith chart.
A Touchstone file provides the input parameters and the input type.
You can also convert and list scattering, admittance, or impedance parameters input by a Touchstone file. The
new PRSYZ command generates a new Touchstone file jobname_SYZ.snp for the network parameters.

as a function of frequency.
1.1.6. Thermal
ANSYS 9.0 includes the following new features and enhancements that expand your ability to perform thermal
analyses.
1.1.6.1. Radiosity Enhancements
The ANSYS radiosity capability has been enhanced to allow symmetry in 2-D planar/axisymmetric and 3-D
models. Prior to ANSYS 9.0, you had to build the full model, both for the solid region and for the radiation surface,
resulting in a significant increase in computational cost. With ANSYS 9.0, you can now solve the radiation problem
based on the full radiation surface and solve the heat conduction problem based on the solid/fluid region with

specified symmetries. As part of this enhancement, you can reduce the number of surface elements by creating
a decimated mesh and generate new SURF251/SURF252 surface elements. See the discussion on Advanced Ra-
diosity in the ANSYS Thermal Analysis Guide for a detailed description of this procedure.
1.1.7. Solvers
ANSYS 9.0 includes the following new enhancements that improve solution procedures and features.
1.1.7.1. Distributed ANSYS
ANSYS 9.0 adds Distributed ANSYS to the Parallel Performance for ANSYS module. In Distributed ANSYS, the
entire solution, including generating the stiffness matrix, solving the equations, and performing the results cal-
culations, runs in parallel. As a result, Distributed ANSYS is very scalable for linear and nonlinear analyses, both
for wall-clock time and equation-solution-only time.
DistributedANSYS'distributedmemoryarchitecturerunsasolutionovermultipleprocessorsonsingleormultiple
machines. It decomposes large problems into smaller domains, transfers the domains to each processor, solves
each domain, and creates a complete solution to the model. Because the solutions are running in parallel, the
whole-modelsolutiontakesmuchlesstimetosolve.Thememoryrequiredisalsodistributedovermultiplesystems
so that the peak memory required on any one machine is greatly reduced, making large-model solutions possible
on lower-end computers with limited memory.
Distributed ANSYS includes two sparse solvers (the sparse and the distributed sparse direct solvers), a PCG
solver, and a JCG solver. The sparse solver can still run in shared-memory parallel mode, and the distributed
sparse, PCG, or JCG solvers can run in distributed-memory parallel mode. Distributed ANSYS is available for linear
structural analyses, nonlinear structural analyses, and full transient analyses for single field structural and single
fieldthermalanalysis.SeethenewDistributedANSYSGuidetolearnhowtoconfigureyoursystemtorunDistributed
ANSYS.
Distributed ANSYS is available on HP 64-bit platforms, SGI 64-bit platforms, and Intel Linux 32-bit and 64-bit
platforms. A beta version of Distributed ANSYS is available for most other ANSYS platforms, including 32-bit
Windows.
1.1.7.2. MSAVE Enhancements
TheMSAVEcommandnowsupportsSOLID45andSOLID185elements(brickshapesonly),inadditiontoSOLID92,
SOLID95, SOLID186, and SOLID187.
1.1.7.3. Results File Splitting for Large Models
You can use the RSPLIT command to decompose a large results file (typically generated from an assembly
model run across a server or cluster of machines) into smaller files that can be easily postprocessed. For example,
for an assembly, you could create separate results files for each part. See Splitting Large Results Files in the ANSYS
Basic Analysis Guide for more information.
1.1.7.4. Sparse File Splitting Changes
At ANSYS 9.0, the sparse solver files are no longer split at different sizes than other ANSYS files. Prior to ANSYS
9.0, all 64-bit machines split sparse solver files at just under 8 GB, while 32-bit machines split sparse solver files
at just under 2 GB. Also prior to ANSYS 9.0, you could not override the maximum split file size of 8 GB for 64-bit
systems or 2 GB for 32-bit systems. In ANSYS 9.0, the sparse solver files are now split the same as other ANSYS
files. By default, the file split size is over 100 GB, so you should almost never see split files. Linux 32-bit systems
follow the same split size as other systems and will no longer split files at 2 GB.

1.1.8. Usability
ANSYS 9.0 includes the following new features and enhancements that increase the usability and the overall
functionality of the program.
1.1.8.1. Improved Surface Operations
Surface calculations in postprocessing (/POST1) now support a cylinder option. Issue the SUCR command to
specify a cylindrical surface centered at the working plane origin, and extending infinitely in the positive and
negative Z directions. For more information, see Section 5.3.2: Surface Operations in the ANSYS Basic Analysis
Guide.
1.1.8.2. Enhanced Coordinate System Support for Function Loads
Prior to this release, function loads and other function-builder parameters were available only in Cartesian co-
ordinate systems (RSYS,0). ANSYS now supports them in local coordinate systems (Cartesian, cylindrical, solution,
user-defined, etc.). For more information, seeSection 2.6.15: Applying Loads Using Function Boundary Conditions
in the ANSYS Basic Analysis Guide.
1.1.9. Programmers' Manual Updates
ANSYS 9.0 includes the following programmers' manual updates:
Subroutines provided for your convenience in the Guide to ANSYS User Programmable Features and the Guide to
Interfacing with ANSYS have been updated to use alternative memory management routines and to reflect
changes in the results file format. All routines and functions documented in the Programmer's Manual Set have
been updated to reflect the current source code.
To see specific changes in a file, ANSYS recommends opening both the old and current files (using a text editor
that displays line numbers), then comparing the two to determine which lines have changed. You can copy the
updated files to your system by performing a custom installation of the ANSYS program.
1.1.9.1. Interfacing with ANSYS Updates
The results file format as described in Section 1.2 of the GuidetoInterfacingwithANSYS--fdresu.inc is a description
of the results file contents--has been updated to support results files generated by solving very large models.
The results file format has been modified as follows:
• More of the index tables are 64-bit, so they take two integer words in the file rather than one as in prior
results files. Some of the header records have also increased in size.
• All of the pointers in the index tables are relative pointers; that is, they point to data relative to the current
file location and the physical pointer to the data is computed as relative pointer + offset.
The new access routines as documented in Section 2.3 have also been updated accordingly.
1.1.9.2. Guide to User-Programmable Features Updates
Section 1.13 of the Guide to ANSYS User Programmable Features has been updated to reflect the alternative
memory management routines.

ection.
PSOLVE -- Performs a partial solution. The command now supports partial solutions for the QR damped ei-
gensolver, allowing a prestressed modal analysis (PSTRES,ON) following a large deformation (NLGEOM,ON)

model. All surface-operation functionality is available for your cylinder, and the surface automatically extends
along the plane's Z-axis, to the opposite ends of your model.
SXGEOM -- Defines a geometry parameter created with ANSYS ParaMesh as a DesignXplorer VT (Variational
Technology) input variable. The command has new options to set the minimum and maximum of the input
variable, to set the reduction option, and to set the deviation order.

data curves for any of the disciplines supported by curve-fitting operations.
1.1.10.3. Undocumented Commands
The following command is no longer documented and may be removed from ANSYS at a future date:
PLSP -- Use the PLSYZ command instead.
1.1.11. ANSYS Elements
This section describes changes to elements at the ANSYS 9.0 release.
1.1.11.1. New Elements
ANSYS has been enhanced with the following new elements:
SOLSH190 -- A 3-D solid shell element that has translational degrees of freedom and eight-node brick con-
nectivity, thus eliminating the problem of transitioning from solid to shell elements. The element performs
well in simulating shell structures with a wide range of thicknesses (from extremely thin to moderately thick).
You can use it for both flat plate and curved shell models.
FOLLW201 -- A one-node 3-D element that you can overlay onto an existing node with physical rotation de-
grees of freedom. The element specifies external forces and moments, following the deformation of the
structure. The element contributes follower load stiffness terms in a geometrically nonlinear analysis
(NLGEOM,ON).
SURF251/SURF252 -- Radiosity surface elements allow you to use symmetry to model radiation problems
and significantly reduce the problem size. You solve the radiation problem based on the full radiation surface
and solve the heat conduction problem based on the solid/fluid region with specified symmetry. You must
use the RSURF command to generate these elements. See the discussion on Advanced Radiosity in the ANSYS
Thermal Analysis Guide for a detailed description of this procedure.

1.1.11.2. Modified Elements
Changes and enhancements to the capabilities of the following elements have occurred:
SHELL91 -- For this 8-layered shell element, ANSYS no longer supports the old (prior to ANSYS 5.2) format
for real constants. KEYOPT(2) is no longer recognized and is now undocumented; previously, it was necessary
to set KEYOPT(2) = 1 before providing real constant values in the old input format.
HF119andHF120--Thesehigh-frequencyelementsnowsupportaSpecificAbsorptionRate(SAR)calculation.
SURF151 / SURF153 -- If a single PLANE element lies beneath SURF151 or SURF153, you can automatically
set the element behavior (plane stress, axisymmetric, or plane stress with thickness [including TKPS if applic-
able]), to that of the underlying solid element by specifying KEYOPT(3) = 10. This option is valid only when
a single PLANE element lies beneath the SURF element. For example, if you apply a SURF151 or SURF153
element over a PLANE77 (thermal) element whose nodes are also used in the definition of a PLANE82
(structural) element, a warning appears and the load is not applied to the element.
SURF154 -- A new KEYOPT(2) setting applies pressure loads to the element faces according to the local co-
ordinate system, as follows: face 1 in the local X direction, face 2 in the local Y direction, and face 3 in the
local Z direction. (Faces 4 and 5 are unaffected.) When using KEYOPT(2) = 1, a local coordinate system must
be defined for the element.
CONTA178 -- KEYOPT(2) of the CONTA178 node-to-node contact element controls which contact algorithm
is used. The options for KEYOPT(2) have been reordered to be consistent with the surface-to-surface and
node-to-surface contact elements (CONTA171 to CONTA175). As a result, the new default contact algorithm
for this element is the augmented Lagrange method.
SHELL181 -- This shell element now supports preintegrated general sections, where the relationships of
generalized stresses to generalized strains are input directly. When the element is associated with the prein-
tegrated section type (SECTYPE,,GENS), thickness or material definitions are not required.
BEAM188/BEAM189--Thesebeamelementsnowsupportnonlineargeneralsections,wheretherelationships
of generalized stresses to generalized strains are input directly. When the beam element is associated with
a generalized beam (SECTYPE,,GENB) cross section type, the relationship of transverse shear force to the
transverse shear strain can be nonlinear elastic or plastic, an especially useful capability when flexible spot
welds are modeled.
PLANE223, SOLID226, and SOLID227 -- These coupled-field elements can now account for Seebeck, Peltier,
andThomsonthermoelectriceffectsinadditiontoJouleheating.Theycannowalsoaccountforbothtransient
thermal and transient electrical effects in a transient analysis.
1.2. Guidelines for Upgrading to the ANSYS 9.0 Family of Products

KEYOPT(2) is no longer recognized and is now undocumented; previously, it was necessary to set KEYOPT(2) =
1 before providing real constant values in the old input format.

1.2.1.2. KEYOPT(2) Revised for CONTA178
KEYOPT(2)oftheCONTA178node-to-nodecontactelementcontrolswhichcontactalgorithmisused.Theoptions
for KEYOPT(2) have been reordered to be consistent with other contact elements. As a result, the default contact
algorithm for this element is now the augmented Lagrange method instead of the Lagrange multiplier method.
See the CONTA178 element description for complete details on KEYOPT(2) settings.
1.2.1.3. Cast Iron Plasticity Element Support
The enhanced cast iron plasticity material model does not support elements LINK180, SHELL181, BEAM188,
BEAM189, SHELL208, and SHELL209. For more information, see Section 1.1.2.4.1: Cast Iron Plasticity.
1.2.1.4. Fluid-Solid Interaction Analysis Using MpCCI
The fluid-solid interaction analysis method using MpCCI is no longer supported.
