Fatigue Prep Overview

The Fatigue Prep custom wizard generates ADAMS output files from a flexbody transient run, which can then be used in nCODE Fatigue software. Finite element fatigue requires that flexbody mode shapes be an nCODE FES file, and the flexbody modal participation factors be "n" number of DAC files, where each DAC file contains the time history of a single mode's modal participation factor.

From the FlexTools menu, select Fatigue Prep to display the Fatigue Prep custom wizard.
