I need to do an FEA analysis on an assembly but I can't figure out how to isolate the mass load on a single area instead of having it equally distributed throughout the entire surface. Thanks!
You can sketch an outline of the area you want to study right on the face the force will be applied to. (If you can't sketch on the surface, you can sketch on a plane normal to the surface). Then you go to Insert>Curve>Split Line and this will project your sketch onto the chosen surface and isolate the region you've outlined. This will give you a smaller section of the surface to which force can be applied.
It only works on individual parts but I couldn't find the Split Line feature on an assembly. Is there another way to do it in assembly? I'd like to do an analysis of the entire assembly as a whole.
split at the part and then put in your assembly
