By default, Fatigue Advisor estimates cyclic material properties from the type of material you specified and its tensile ultimate stress. However, this is purely an approximation. If you want to increase the accuracy of your analysis, you can use an ASCII file to enter specific cyclic material properties. To do so, use thesim_fatigue_external_matdata configuration option.

If you set the above option, you need to create and assign a material to your model in Creo Simulate. You then assign your ASCII file the same name as the material you created and give the file a .mat extension. You place this file in the same directory as your .prt or .asm file. This file is used to obtain the model material during analysis. For additional information, visit Technical Support at www.ptc.com.
