Hello all, I have a question about the equations behind the difference between loadcases that use forces vs loadcases that use prescribed displacements. I am aware that these two loadcases lead to different results on Optistruct, but have found very few info in the help about it. I did a simple test watching the behaviour of a part under torsion and bending when I try to optimize it on Optistruct (minimize mass, Von Mises static constraints, gauge optimization). -When "enforced displac
