Thanks Rob. That's very useful information in relation to the hexahedral mesh, I'll investigate that. I managed to run a tetrahedral-based dynamic mesh 6dof version of my MPM simulation without the VOF model turned on and I obtained good results. I just had to add the calculated buoyancy force directly in the UDF using prop[SDOF_LOAD_F_X]. Would the recommentation for situations like this be to stay with tetrahedral meshes, or should I not have any major issues using hexahedral cells? Thanks again for your time.
