  Hi, I tried to implement the Doi-Edwards model for an integral viscoelastic simulation for a shell model by switching to Doi-Edwards model in the "Material Data File" in Ansys polymat. After I saved the new Material Data File I tried to input the data with polydata_core.exe but I wasn't able to select "switch to Doi-Edwards model" (see picture). What can I do?

  Hi,
  It shows the default KBKZ model. Can you load that mat file in polydata GUI and check?

    Hi, thanks for helping me out.
    The polydata GUI shows the same.

    Only polymat shows, that Doi-Edwards was choosen.

    The polyflow.lst after the simulation also shows that the simulation was calculated with the KBKZ-model:

  I see now. I think the Doi-Edwards integral model is not compatible with shell model.
