I have built a simple cylendrical shell. I am trying to run a random vibrational analysis. I started out just by choosing modal damping and letting the simulation run. Since then, I have changed just about every parameter I could think of just to get it to work, and nothing helps. The error message I get every time is:
Damping cannot be defined as zero for any modeshape.
The simulation does mesh my part. I have not applied any fixtures or forces (I added some in later just to see if that would solve the problem, but it doesnt). I have changed the frequency of the modes that I am trying to find so that none of them are zero. I think Solidworks is supposed to find these for me, but it apparently thinks that they are all zero.
Has anyone gotten this error before? I even rebuilt my part to see if I had done something crazy, and that didn't help either. Tips/advice/suggestions welcome!
