when i run a fatigue simulation, why are the materials all grayed out? I have all my components defined in a fatigue study with standard and custom materials. I do not have fatigue data for all the parts so ive been using the "derive from material elastic modulus-based on ASME austenitic steel curves" option. I do have one part that i have the curve for. However, all my parts are showing as one material. The part i have selected should be SAC 305 and not VT-47
This is intentional and part of the new simplified workflow for fatigue studies in Simulation. The only actions available through the new Apply/Edit Fatigue Data command in a fatigue study in Simulation are modifying the SN curve or viewing the assigned material's properties. If you wish to apply a different material, you must do so in the associated static study (or studies) and re-run the study prior to setting up the fatigue study.
