Fatigue Analysis: No Results Shown
Altair EmployeeHi Friends,
I am attempting to run a fatigue subcase in optistruct, in which case the analysis has 3 loadsteps:
Loadstep 1: Preload a part of the structure.
Loadstep 2: Apply a unit load to another region of the structure.
Loadstep 3: Run a block cycle using the unit load from loadstep 2.
The first two loadsteps are linear-static and the 3rd loadstep (fatigue subcase) references loadstep 2. When i review the results, I see that loadsteps 1 and 2 work (provide meaningful results), but the fatigue subcase keeps showing zeroo damage and infinite lives. I have udpated the FATDEF card to include element sets which are to be considered during the fatigue analysis...
Can you please help me with this? I seen an older post where someone had the same problem but noone replied to his post with solutions.
Thank you!
