Apply the Loads

  1. Right-click on Loads under Subcase 1 and choose New. In this subcase, the load is a 100 KN force applied to the first bolt hole of the bracket in the positive x-direction.
  2. Enter Axial Loading in the Name field.
  3. Select the interior surface of the first bolt hole farthest from the back face and type in 100E3 for Fx.
    Note: In the Display Options section of the Load dialog, you can adjust the size, number, and color of the load symbols that appear in the part display.
  4. Be sure that Subcase 1 below the Subcases list is selected.

  5. Then click OK.

    You can also drag-and-drop different entities in the tree view. For example, the Axial Loading load and the Fixed Back Face constraint can be dropped on top of the Subcase 1 name.

  6. The model should look as shown below.

    You can hide the loads and constraints. Click on Autodesk Nastran menu tab on the top of the CAD interface, and then choose Default Settings under the System panel on the ribbon. Then click Display Options and uncheck the Loads and Constraints checkboxes. They can also be hidden by right-clicking on the Loads or Constraints within the Subcases section in the tree and checking Hide All.
