Tutorial B9: Set Up the Analysis

1. The Inner cylindrical face of the wheel arch is fixed. Use the View Cube to orient the part so that you have a clear view of the bottom face. Right-click on Constraints under Subcase 1 and select New.
   

   All the entities that you will be creating will also appear in Model Entity list. This list will expand as the modeling progresses. The Model Entity list provides a means of easily applying entities to other subcases as well.

2. When the Constraint dialog appears, select the inner cylindrical face.
   
3. Type Fixed Constraint for the Name of the constraint. Change the Coordinate system to Cylindrical and Uncheck the R_r, R _θ , and R_z boxes.
   Note: In the Display Options section of the Constraint dialog, you can adjust the size, number, and color of the constraint symbols that appear in the part display.
4. Be sure that Subcase 1 is selected in the Subcases list, and then click OK. This will automatically add the constraint to Subcase 1.
5. Right-click on Loads under Subcase 1 and choose New. In this subcase, the load is a 50 psi pressure applied to the outer surface of the wheel in the direction normal to the surface.
   
6. Set Pressure as the Load type from the type drop-down.
7. Enter Pressure on Face in the Name field.
8. Select the Outer surface of the wheel and type in 50 psi.
   Note: In the Display Options section of the Load dialog, you can adjust the size, number, and colour of the load symbols that appear in the part display
9. Be sure that Subcase 1 below the Subcases list is selected.
10. Then click OK.
11. In the tree view, right-click on Analysis 1 and select Edit.
12. Type Linear Static Analysis for Name, type Cyclic Symmetry for Title, and select Linear Static for the analysis Type.
13. Ensure that Displacement is checked under Nodal Output Control and Stress is checked under Elemental Output Sets.
14. Switch to the Options tab. Check the box under Cyclic Symmetry, and set the Coordinate system to Cylindrical. Make sure that the coordinate system selected inside the Options tab is the same selected while applying constraint, then click OK.
