Hi,

Select the nodes and then input these commands

F,All,MX,100 ! 100 - moment about X axis
F,All,MZ,200 ! 200 - moment about Z xis

That will work fine with beams and shells but will doing nothing with
elements that don't have rotational degrees of freedom. I think the
easiest way to apply a moment to a face of a body meshed with solid
elements is to use the multipoint constraint capability of the contact
elements. See section 9.3 of the Contact Technology Guide.
