Apply Global Fatigue Solution Settings

Apply fatigue solution settings to the entire assembly.

Global default fatigue solution settings are applied automatically when the project is opened, but some adjustments can be made if needed.

  1. In the main toolbar, click Settings > Default fatigue solution settings.
  2. In the dialog, choose one of the following options:
    Option Procedure
    Fatigue Method The following methods are available:
    • Uniaxial
