Does that appear only for frequency analysis or for other analyses as well?

  I am not tried it in other type of analysis, but it does not happen in static analysis.

    I think this relates to the size of the gap between 'contacting' bodies or surfaces. If the gap gets too big, then the software has a problem. Are you meshing with shells?
