Target is the Designer Analyst
Designer Analyst
Someone that splits time between Design and Analysis.
Does not do advanced analysis. It is either not needed by the customer or is covered by a dedicated analyst using FEMAP.
Often the “super designer” at small companies being asked to do more faster.
Desires
Easy of use.
Geometry only commands.
Extended help and guidance relative to “dedicated analysis” tools such as FEMAP.
Familiar interface.
Understandable results.

Designer Products - Differences With Analysis Products
Geometry Focused – Designers will work only with Geometry (i.e. Force on face). You will need a high end product (FEMAP, NX Advanced Simulation,) to work directly with nodes and elements.
Single Solver – SE Simulation will use only NX Nastran. Femap supports multiple solvers.
Designer Language Rather than Analyst Language
Easy Geometry Modification Capability –Synchronous Technology has interesting potential for CAE model preparation.
More Process Oriented – UI organized to step you though a process. More help and suggestions to guide the designer when problems occur.

Analysis Steps
Model Preparation and Simplification– Modify “designed” geometry to meet the needs of analysis.
Preprocessing – define the loads, constraints, material properties and connections between assembly parts.
Mesh – define the type of mesh to be used and refine it as needed.
Solve – The solve occurs when the FEA model composed of the mesh, loads, and constraints are passed to NX Nastran for analysis.
Post Processing – examine the results from NX Nastran using various visualization and reporting tools.

Solid Edge Simulation

A Quick Analysis
Demo
(At PLM World, a demo was given here)

Environment
A new Tab and Ribbon bar in Part, Assembly, SM environments.
integrated into these environments
(turned on with License)
A Simulation navigator is provided for Studies
Can also be used as an alternative to the ribbon bar for command access.

Environment Simulation Tab
Part – Analysis Tab
Assembly – Analysis Tab

Study Navigator
Provides a tree view with drag and drop functionality for working (create, edit, delete, copy, etc...) with FEA Analyses/Studies, load sets, and constraint set results
It is important to note that an analysis study can be totally defined through the Study Navigator
With a RMB click the user can define geometry, loads, constraints, mesh, etc….

Study Navigator
A Study can be created by RMB clicking on “Simulation” in the study Navigator
Once the Study is created the user can easilyrename, copy, delete, modify, solve, or usethe save to Femap .mod file
material can be added or changed

Demo
Study Creation

Mechanical Loads
Covers the available geometry based FEMAP mechanical Loads.
Temperature load (for body only – thermal expansion)
Handles for defining direction, orientation.
Quick bar options for input.

Constraints
The following types of constraints are supported
Fixed
Pinned
No rotation
Sliding Along Surface
Cylindrical
Valid entities to select are faces, edges, and points (vertex)

Demo

Meshing
Support for 2D Mesh and 3D tetrahedral mesh.
UI options that change between environments (i.e. Sheet metal defaults to 2D mesh)
The “Mesh” commands can be executed from either the command bar or from the study Navigator.
command to set the mesh sizing for edges and faces.

Demo
Mesh
Mesh Sizing

Solve Command
Command to run the analysis (execute NX Nastran)
UI to expose some NASTRAN options (GEOMCHECK)
Key piece of this will be handling NASTRAN errors in a user-friendly way.
Some UI for displaying actual NX Nastran errors for more advanced users.

Post processing – plots and graphics
Colorized plots, contours
Displacement, animation, mode shapes.
Internal and External element display
Display of results in context of assembly, other graphics.

Color Bar
Provide additional indicators for key material properties.
Provide color display options with overflow and underflow values.
Saving of color bar options across sessions.
Ability to position color bar at different locations and sizes on the screen.
Grayscale
Rainbow
Stoplight

Probe
Allow the user to probe specific node data.
Creates a tool which can return information about nodes by moving the mouse cursor over the results and their data.
Provide Min-max markers for key stress
Provide table with copy/paste

Reports
Create Report
Similar to Femap Express
HTML Output
Remembers Settings!

Demo
Post Processing
Color Bar
Probe

Assembly connectors
Provide the linear and glued connectors that are supported by Femap and NX Nastran.
Provide an automated tool to connect touching faces in an assembly.
Provide a manual UI for selecting faces on assemblies that will be connected.
Manual Connector

Demo
Connectors

Solid Edge Simulation Assembly
Covers certain special needs for Assemblies not addressed by other projects.
Assembly level features from Traditional assemblies
Traditional Weldments
Assembly default Material
Traditional Weldment brought into Synchronous assembly

Simulation Options
A new “Simulation” tab has been added to the “Solid Edge Options” dialog to display various Solid Edge Simulation options
Default NX NASTRAN options
Default Meshing options
Default Study options
Default Plot options
Default Load and Constraint options
Number of Modes to return

Save to FEMAP
Command to create a Femap .mod file from a Solid Edge Simulation Study.
Transfers loads and constraints, mesh and results.

New “User Assistance”- combined Help and Self-paced Training
For the SE Simulation product, Education Media will implement several enhancements to the user learning experience:
Combined user help and self-paced training-asingle destination for customer learning. Single-source textual and graphic content reduces localization costs for Siemens PLM.
Workflow-based landing pages as anchors to keep new users focused on the order of doing something and providing a link from each step directly to a procedure.
Focused SE Simulation help file: When the user is executing a Simulation command only SE Simulation “User Assistance” is active; removes the clutter of other SE help.
