Overview of the User’s Guide
The Fatigue Module User’s Guide gets you started with fatigue evaluation using COMSOL Multiphysics. The information in this guide is specific to this module for fatigue analysis. Instructions how to use COMSOL in general are included with the COMSOL Multiphysics Reference Manual.
For all other physics and theory, also see the Structural Mechanics Module User’s Guide (or search online).
As detailed in the section Where Do I Access the Documentation and Application Libraries? this information can also be searched from the COMSOL Multiphysics software Help menu.
