How to apply Moment load for solid element.
As per Altair Student Guide:
The correct way to apply a moment to a solid model is to use an RBE2 or RBE3 rigid-body element. The rigid-body element distributes an applied moment into the solid element model as forces.
Don't use RBE2 in this case !
RBE3 is not rigid-body element and that's the correct way to distribute the load.
