  Hello everyone, I am wondering why the results from NLPLWK always show zero. Any suggestions would be appreciated.

  Easiest answer is that the model did not produce any plastic strain...what do the strain and/or stress results show? Mike

  Hi Mike, thanks for your feedback. The strain and stress show no-zero results. Do you have any suggestions on how to address the issue? Thanks!

  None of those are plastic strain. Please show that plastic strain is non zero.

  Did you add a mesh method object and choose the "Sweep" method meshing with "Automatic Thin" or "Manual Thin" option?

  If not that then we need more information on the model. Material model, mesh type, etc.
