How to perform the submodel simulation in Workbench LS-DYNA?

Hi all,

Recently, I am dealing with the submodeling method in Workbench LS-DYNA. I know how to set the keyword snippet for the cut boundary. But when I performed the simulation for submodel, it always failure due to the negative volume. I tried many ways to solve this problem like reduce the time step, change the element formulation, change the hourglass type, but all failed. I think maybe I have some mistakes about the setting in sub-model simulation?

Does anybody know how to solve this problem?

Thank you!
