  2. Hello, Can anyone please let me know how to get/ request rms stress in HM 11, Optistruct Solver? Thank you.
  3. Hello guys, I made an example of Random Response Fatigue Analysis. There are three loadstep in my model and there are FRA, Random and Fatiuge. the results of first two Loadsteps are not error. Though the fatigue subcase can run ,there is no any result in the subcase。 Lcid card refers to the Random subcase. And the Tid card is blank. the PFAT card was estimated by UTS. Would anyone can fix the problem out? 1pl.fem
