Oh okay, in fact I have activated the nodal forces and I think there's no problem for the nodal forces but the nodal moments are always =0. Here is another photo (instead of the video) to show you what I mean:

The face I pointed to in blue is the fixed one and that in red is moving along y (upward). Sure enough, the fixed face (blue) is resisting the upward motion (bending too), so normally we should have a moment My on that face. I'm always getting zeros.
