Submodeling

I am using the lastest version of HyperMesh and doing a non-linear static analysis with large displacement non-linearity. My model is large and I need to focus on a specific local area by importing the global displacements from the global model.

However, the "Submodel" entry is only available to me when i select linear static solver in the subcase.

Am I missing something crucial?

Thanks in advance,

Jamal
