13. ANSYS capabilities

14. Steps to be followed
• Preprocessor
• Geometric modeling
• Material modeling
• Element selection
• Discretization
• Loading and boundary conditions
• Selection of solver
• solving
• Viewing the result

15. Preprocessing
Apply loads and boundary conditions
Cross section for 1D problem and thickness
for 2D problems

16. Element Selection

17. Real constants
The calculation of element matrices requires material properties, nodal coordinate and
geometrical parameters. Any data required for the calculation of element matrix that
cannot be determined from the nodal coordinates or material properties are called real
constants

18. Defining material properties

19. Defining material properties

20. Geometric modeling
1. Top down modeling
2. Bottom up modeling
Bottom –up modeling- Starts with key
points, from which lines, areas and
volumes are generated
Top- down modeling-Starts with a definition of volumes
or areas ( Primitives), which are then combined in some
fashion to create the final shape

21. Geometric modeling

22. Geometric modeling
Ansys will not allow you to delete or modify a lower order
entity if it is attached to a higher order entity

23. Geometric modeling

24. Geometric modeling

25. Geometric modeling

26. Geometric modeling

27. Geometric modeling

28. Element Selection and types-1D
L
Length is very high compared to height and thickness

29. Element Selection and types-2D
L
h
Length and height are comparable and thickness is negligible

30. PLANE STRESS

L-Length
t-Thickness
h-Height
Length, thickness and height are comparable-3D Elements

36. Finite element modeling

37. Bar Beam Truss Frame
Single Member Single member Many members
connected by pin joint
Many members are
connected by welding or
bolting
Take Loads
along the axis
Take loads
perpendicular to axis
Loads are applied at the
joint, can take force
along the axis of the
individual member
Multi force member can
take both axial and
perpendicular loads
One DOF per
node

Two DOF per Node
(Translation,
rotation)
( for 2Dimensional
structure)
Two DOF Per node
(Translation)
( for 2Dimensional
structure)
Three DOF per node
(2 Translation and
one rotation)
( for 2Dimensional
structure)
