Hi all,

I would like to simulate a lab-style fatigue test using the implicit solver on LS-Dyna. I have created a model for a fatigue test specimen and run the file using LS-Run. I am left with a d3plot and a d3eigv file, but no d3ftg file to see the calculated cumulative damage ratio and estimated fatigue life. The message file from LS-Run indicates an error (Error 40435 (SOL+435) wrong in reading d3eigv), and I can't find any information on how to correct the issue.

Any tips?
