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!

Can you check the message file to make sure the ISFL file has been loaded into the sub-model?
I noticed that there is a space in the path of the ISFL file.
Hi cxquan,
I double check the message file which shows that there is no any error or warning pop out by loading into the sub-model. Do you have any other advice? The sub-model always show the negative volume error, even I changed the element formulation and other ways.
Thanks!
Check the settings of solver units under Analysis Settings. Make sure both model use the exactly same units.
