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