The document discusses Anthropic's Simulation and ANSYS software capabilities. It introduces ANSYS, describing its capabilities for linear static stress analysis, vibration analysis, and thermal analysis. It outlines the basic steps for performing a complete ANSYS analysis, including preprocessing tasks like geometric modeling, applying loads and boundary conditions, element selection, and material property definition before solving and viewing results.

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

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
