Apply Local Fatigue Solution Settings

Apply fatigue solution settings to a group of parts in the assembly.

  1. In the Project tree, right-click Project solution settings and choose Edit.
  2. Click New.
    A new group appears in the group list.
  3. In the modeling window, select one or more parts for the group.
    Tip: You can also select parts from the Project tree.
  4. Optional: You can choose Exclude all to exclude all parts in the assembly.
  5. Optional: You can activate the Include all seam welds checkbox to include all seam welds in the assembly.
  6. In the dialog, choose one of the following options:
