Stress/Strain results not showing when loading OP2

Altair Forum User

Hello there,

 

I am trying to simulate the residual stresses and strains of a composite panel after a temperature change to evaluate the springback. To do so, I am using HM as the pre-processor and HV as the post-processing tool, and MSC Nastran as the solver. I am currently running SOL 400 (non linear implicit) analysis and I get my OP2 file and f06 just fine. When I load my results (bdf and op2) in Patran I can see them fine, but when I try to do so with HV, I can only visualize displacements and SPC forces but not Stress or Strain. It seems as those results where not loaded into HyperView. What can I do to solve this?

If it helps, here is the beginning of my bdf file.

Thanks in advance.
