I previously analyzed a model that had various pressure loads/load curves using transient stress (direct integration) analysis type and everything ran correctly. Since then I wanted to run the same model using MES with nonlinear material model analysis type, so I simply changed the analysis type and changed the element definitions. I had to redo the load curves because for some reason they didn't transfer over. So I ran the model and got some warnings that said "missing hardening modulus for material XXX", but I didn't get any errors. That is one problem but the biggest problem is there are no loads being applied to the model in the results tab, hence no stress. What could be the problem?
