@mishal49 sorry for the late reply. Are you still stuck at the same point?

Comparing your case with the elastic-tube-3d tutorial (using meld), I notice the following:

  • You are using a nearest-neighbor mapping, instead of a nearest-projection, which should be more accurate. Why? The solver combination you are running supports it. Note that in the config.yml of CalculiX, you have removed the connectivity.
  • You are using a parallel-implicit scheme, instead of a serial-implicit, which should be more stable. Why? This has nothing to do with parallelization.
  • In the tutorial, we are using IQN-IMVJ, you are using IQN-ILS, as @uekerman suggested. This may be something to reconsider in the new context. You also currently accelerate both Force and DisplacementDelta, and reuse more iterations and time windows (which should be good).
  • You have generated a new CalculiX case, which I don’t have the skills to evaluate. What was your goal there? Maybe one of the @calculix-users could help (join that group, if you are one).
