I have a model of fractured bone which is fixed by particular plate-screw system. I set some frictional contact properties there. Then I tried running the simulation on the model with linear static analysis as my load step of choice. I used Altair Hyperworks with its Optistruct solver.

I can get the result from linear static with simulation time only around 2 hours and the file was only as big as 700 MB. However, when I tried running the same model with the nonlinear static analysis, the simulation kept producing bigger and bigger files, even more than 200 GB. It eventually ate up all my storage, and after that the simulation just stuck there.

I have read some information saying that nonlinear static analysis is recommended whenever we applied friction contact properties. But in my case, can I just use linear static analysis?
