I had the same problem and I think I solved it.

  1. In Mechanical, go to File > Options, a window will open. 
  2. On the left side, choose "Analysis settings and solution", scroll down and in the section Analysis data management > Scratch solver files directory, check if you have a files path.
  3. If you don't have a files path, choose one.
