ANSYS Workbench: Mechanical Examples

1. ANSYS Workbench: Mechanical Examples

2. Step 1. Opening ansys workbench • Overview: • Start > ANSYS Workbench • Create Static Structural analysis system

4. 2 1

5. Double click

7. [Optional] Note on save as … • Do not save to a network drive location • //server/share/folder/file.wbpj • Instead used a local drive or mapped network drive: browse computer, for example • U:/folder/file.wbpj • Reason: when solver tries to start, it will fail if a file it needs is in a network drive location (even if there is an equivalent mapped location). Can save and re-open from the mapped location. To view where your files are, • Workbench menu > View > Files

8. Step 2. Geometry • Overview: • Sketch • Draw • Dimension • Generate • Extrude • Generate • Close the DesignModeler window

9. Double click, wait, then click 1 2

10. Click XYPlane

11. Click new sketch

12. Click Z axis

13. Click sketching tab

14. [Optional] Click Settings; Check boxes grid on and snap; Major grid spacing 1 m; Minor steps 10; Click Draw

15. Note: navigating 3d view • Zoom: mouse scroll wheel, or click buttons for box zoom, slide zoom, fit all • Tilt: press middle mouse button (scroll wheel) and move mouse • Pan: Ctrl+Middle mouse button

16. Note: making mistakes • Use Undo/redo on toolbar • Sketching > Modify > Trim to remove mistakes • Zoom in close to make sure lines are closed. Fix with trim and corner.

17. Click Draw Rectangle

18. Click one corner, then opposite 2 1

19. Click Dimensions

20. Dimension steps • Click the entity to dimension • Click to place the dimension label • Find the label in Details View • Select and enter the value

21. Dimensions 1 2 3

22. Draw and dimension circle

23. Click Modeling

24. Click on the sketch

25. Click extrude

26. Under geometry, click apply

27. Select depth and enter a value

28. Generate

29. Close the window

30. Step 3: Model and setup • Overview: • Mesh • Create sizing rules • Update mesh • Loads • Insert pressures

31. Double click

32. Wait till you see …

33. Select mesh. Change relevance center or element size. 1 2

34. [Optional] More advanced rules: Right click mesh and insert a rule.

35. Update mesh. (Toolbar or right click)

36. Note on mistakes in meshing and solving: if mesh is too fine and never finishes, Start > run > taskmgr. Kill high CPU process. Increase element size and retry.

37. Example medium relevance mesh.

38. Right click Static Structural > Insert > Pressure

39. Follow the yellow boxes (unfinished)

40. Click geometry value, click a face, then click apply 2 3 1

41. Select magnitude value and enter -100e3

42. Repeat (or duplicate and select differenct face)

43. Step 4: Solving and viewing results • Overview: • Solve and wait • Insert results • Update results • View results

44. Click solve, wait, and check for errors. Warnings are ok, errors are bad. 1 2

45. 2 1

46. Insert a result field: right click solution > stress > maximum principal

47. Right click solution > evaluate all results

48. Select maximum principal stress. Note ratio of max to min values.

49. Advanced step: Parameters.If the box is checked, parameter will be controlled differently.
