Invalid/Missing Stress life curve

      I am using PLA material for my analysis. I plotted the SN curve but when I am solving the analysis, I get the above error for fatigue tool, invalid/missing stress life curve.

      How do I resolve the issue.

      Hi,

      Please see if the following link helps:

      https://innovationspace.ansys.com/forum/forums/topic/module-invalid-or-missing-stress-life-curve/

      Also does it work with normal Structural Steel (Ansys material) that has SN curves defined?

      If yes, then your S-N data (and other properties) might be wrong or missing.

      All the best

      Erik
