      Hi

      You need a moment reaction probe scoped to the fixed support as shown below (MZ does no exist for 3D elements henze zero) to get the moment reaction on that face:

      Make sure also the nodal forces are saved:

      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.

      So 3D elements do not have any rotational degrees of freedom, hence moments do not apply to them. Use as I showed the moment reaction on that BC to get the moment reaction. See below


      Thank you
