Tutorial B3: Set Up a New Subcase

  1. Right-click on Subcases and select New.

  2. Click OK to create a new blank subcase.
  3. In the tree view, right-click on Constraints and select New.
  4. Change the Name to Fixed Holes and select the curves defining the holes at the right end of the beam.

  5. Click both Subcase 1 and Subcase 2 from the Subcases list. This will add this constraint to both subcases.

  6. Click on New button.
  7. Change the Name to Fix in Y Direction.
  8. Additionally, ensure that Subcase 1 is selected in the Subcases list.

  9. Select the three edges of the beam opposite to the side with the holes.

  10. Click on Free button and select Ty to fix the channel in the enforced Y direction.
  11. Click on Duplicate button. Notice that the selection of three edges of the beam opposite to the side with the holes is retained.
  12. Change the Name to Fix in X Direction.
  13. Ensure that Subcase 2 is selected in the Subcases list.

  14. Click on Free button and select Tx to fix the channel in the enforced X direction.
  15. Click OK.

    Constrain the same nodes/surfaces/curves in the direction of the enforced displacement/rotations. It is important that only the nodes that have the enforced displacement are constrained in the direction of the displacement. All other constraints will be treated as actual boundary conditions.

    In the next steps we will apply loads.

  16. Right-click on Loads and select New.
  17. Change the Name to Y Displacement.
  18. Change the Type drop-down to Enforced Motion and make sure Sub Type is set to Displacement.
  19. Additionally, ensure that Subcase 1 is selected in the Subcases list.

  20. Right-click inside the Selected Entities box and check Select Edges.
  21. Select the three edges of the beam opposite to the side with the holes by using box selection method. It will select only those edges.

  22. Under Load Definition, enter 0.01 in the Ty input box.

  23. Click the Duplicate button.
  24. Change the Name to X Displacement.
  25. Additionally, ensure that Subcase 2 is selected in the Subcases list.

  26. The same three edges of the beam opposite to the side with the holes will be copied. The previous load will be shown and the load symbol (arrows) will display. Change the Magnitude under Load Definition, by entering 0.025 in the Tx input box.

  27. Click OK.
