  3. I want to enable the GPU accelerator for a simulation involving a hyperelastic material model, but I seem to be activating Partial Pivoting Logic which precludes the GPU from being used. How can I use my GPU in conjunction with my current analysis setup?

      The help states that Partial Pivoting Logic will be activated if the mixed u-P formulation is used (help/ans_dan/gpusupport.html#nvidiahardware). In order to prevent this formulation from being activated, provide a small value for the material incompressibility parameter, d (e.g., use d = 0.001). This will prevent the mixed u-P formulation from being activated by the solver and your GPU will also be used in the solve as well.
