1. The document provides an introduction to using ANSYS software to perform finite element analysis (FEA). It describes the basics of solid modeling, meshing, applying loads and boundary conditions, and obtaining results in ANSYS. 2. The document then provides examples of tutorials for performing various structural and thermal analyses using the ANSYS software, including static stress analysis of plates and blocks, frame analysis with multiple materials, truss analysis, modal analysis, and buckling analysis. 3. The tutorials follow the typical ANSYS FEA procedure of preprocessing such as modeling, meshing and applying material properties; solving; and postprocessing to view and interpret results. They demonstrate how to use the various tools in ANSYS to

SOLID MODELLING:
Definitions
–A solid model is defined by volumes, areas, lines, and keypoints.
–Volumes are bounded by areas, areas by lines, and lines by keypoints.
–Hierarchy of entities from low to high as
keypoints < lines < areas < volumes
–You cannot delete an entity if a higher-order entity is attached to it. Also,
a model with just areas and below, such as a shell or 2-D plane model, is
still considered a solid model in ANSYS terminology.

2. 2
METHODS OF SOLID MODELING
There are two approaches to creating a solid model in ANSYS, Top-down and Bottom-up
• Top-down modeling starts with a definition of volumes (or areas), which are then combined in
some fashion to create the final shape.
Bottom-up modeling starts with keypoints, from which you ―build up‖ lines, areas, etc.
PRIMITIVES
The volumes or areas that you initially define are called primitives, which are basic entities for
the
top-down method. ANSYS contains the following 2D and 3D primitives:

3. 3
WORK PLANE (WP)
Primitives are located and oriented with the help of the working plane. The ―WP‖ in the prompts
stands for Working Plane — a movable reference plane used to locate and orient primitives.
By default, the WP origin coincides with the global origin, but you can move it and/or rotate it to
any desired position by using following options:
Utility Menu> WorkPlane> Offset WP by increment >
Utility Menu> WorkPlane> Offset WP to >
Utility Menu> WorkPlane> Align WP with> XYZ Locations >
BOOLEAN OPERATIONS
The final shape of an object is usually not as simple as primitives. However,
it is likely doable to combine a number of primitives through a series of
proper Boolean operations. The ―input‖ to Boolean operations can be any
geometric entity, ranging from simple primitives to complicated volumes
generated in previous steps.
Boolean operations are computations involving combinations of geometric
entities. ANSYS Boolean operations include add, subtract, intersect, divide,
glue, and overlap. •All Boolean operations are available in the GUI:
Main Menu > Preprocessor > Modeling > Operate > Booleans
By default, input entities of a Boolean operation are deleted after the
operation.

4. 4
Add: Combines two or more entities into one.
Glue: Attaches two or more entities by creating a common
boundary between them, which is useful when you want to
maintain the distinction between entities (such as for different
materials).
Overlap: Same as glue, except that the input entities overlap
each other.
Subtract: Removes the overlapping portion of one or more

5. 5
entities from a set of ―base‖ entities, which can be useful for
creating holes or trimming off portions of an entity.
Divide: Cuts an entity into two or more pieces that are still
connected to each other by common boundaries. The ―cutting
tool‖ may be the working plane, an area, a line, or even a
volume. Useful for ―slicing and dicing‖ a complicated
volume into simpler volumes for brick meshing.
Intersect: Keeps only the overlapping portion of two or more
entities.
Partition: Cuts two or more intersecting entities into multiple

6. 6
pieces that are still connected to each other by common
boundaries, e.g., to find the intersection point of two lines and still
retain all four line segments, as shown. (An intersection operation
would return the common keypoint and delete both lines.)
FINITE ELEMENT DISCRETISATION
Finite Element Discretization or Meshing is the process used to ―fill‖ the solid model with nodes
and elements, i.e, to create the FEA model. Remember, you need nodes and elements for the
finite element solution, not just the solid model. The Solid Model in CAD does NOT participate
in the
finite element solution.
ELEMENT TYPE
The element type is an important choice that determines the following element characteristics:
• Degree of Freedom (DOF) set. A thermal element type, for example, has one dof: TEMP,
whereas a structural element type may have up to six dof: UX, UY, UZ, ROTX, ROTY, ROTZ.
• Element shape -- brick, tetrahedron, quadrilateral, triangle, etc.
• Dimensionality -- 2-D solid (X-Y plane only), or 3-D solid.
• Assumed displacement shape -- linear vs. quadratic.
To define an element:
Main Menu>Preprocessor>Element Type> Add/Edit/Delete>Add

7. 7
MESHING METHODS :There are two main meshing methods: free and mapped.
Free Mesh–Has no element shape restrictions.
–The mesh does not follow any pattern.
–Suitable for complex shaped areas and volumes.
–Suitable for complex shaped areas and volumes.
–Volume meshes consist of high order tetrahedral (10 nodes), large dof.
Mapped Mesh–Restricts element shapes to quadrilaterals (areas) and hexahedra
(volume)
–Typically has a regular pattern with obvious rows of elements.
–Suitable only for ―regular‖ shapes such as rectangles and bricks.
Mesh Density Control
ANSYS provides many tools to control mesh density, on a global and local level:
–Global controls: SmartSizing; Global element sizing; Default sizing
6
–Local controls: Keypoint sizing; Line sizing; Area sizing
To bring up the MeshTool:
Main Menu > Preprocessor > Meshing > MeshTool
SmartSizing: by turning on SmartSizing, and set the desired size level. Size level ranges from 1
(fine) to 10 (coarse), defaults to 6. Then mesh all volumes (or all areas) at once, rather than one-
byone.
Advanced SmartSize controls, such as mesh expansion and transition factors, are available by
Main Menu>Preprocessor>Meshing>Size Cntrls>SmartSize>Adv Opts
Global Element Sizing: Allows you to specify a maximum element edge length for the entire
model (or number of divisions per line):
Go to ―Size Controls‖, ―Global‖ ,and click [Set] or
Main Menu>Preprocessor>Meshing>Size Cntrls>ManualSize>Global >Size

8. 8
Material Properties
Every analysis requires some material property input: Young‘s modulus (EX), Poisson‘s ratio
(PRXY) for structural elements, thermal conductivity (KXX) for thermal elements, etc.
To define the material properties:
Main Menu>Preprocessor>Material Props>Material Models
ANSYS FEA PROCEDURE
In general, a finite element solution may be broken into the following three stages.
• Preprocessing: defining the problem; the major steps in preprocessing are given below:
Define keypoints/lines/areas/volumes (Solid Modeling)
Define element type and material/geometric properties
Mesh lines/areas/volumes as required
• Solution: assigning loads, constraints and solving;
Apply the loads (point or pressure), Specify constraints (translational and rotational)
Finally solve the problem.
• Postprocessing: further processing and viewing of the results;
Lists of nodal displacements and show the deformation
Element forces and moments
Stress/strain contour diagrams

TRANSFER IN SQUARE PLATE
AIM :
Determine the temperature distribution in a square plate of side 2m and thichness1m with
thermal conductivity K=25 W/m 0
C and convection film co-efficient h=20 W/m2 0
C.The
convection takes place on the right edge of the plate with free stream temperature of 50 0
C.The
left edge of the plate is maintained at a temperature of 100 0
C and the top and bottom edges are
insulated.
