Error during parallel computation

  I'm doing a 6dof simulation with dynamic mesh using 32 partitions, and i'm stuck with this error.
  
  Every time i have to re run the simulation from the previous timestep saved and then waiting until the new error appears. How can i manage this poignant situation?
  
  Many thanks for answering

  Hello,
  
  -Whether the same error occurs while previewing the dynamic mesh?
  - Is the error reproducible?
  - Is it happening for this particular case of observed for other cases as well?
  Check transcript file for Cell Skew and Orthogonal Quality, if they are far away from an acceptable range consider improving the mesh first.
  Also, share some more information such as mesh type, dynamic mesh settings (smoothing/remeshing) etc.
