To find out what forces a component might experience within a model, the "List Result Force" tool can be used. However, the results might not appear as expected.
A static study of a cube stacked on top of another cube with a gravity load is used as an example in the screenshots below.
If the "Reaction Force" is used between the two components, the results will display a reaction force of zero. This is expected since within a model, the forces will have to equate to zero. Otherwise the load would cause the body to move and the assumption of a static equilibrium would be violated.
The "Reaction Force" will only display results when faces or edges that are constrained by fixtures are selected. All other faces and edges will display the expected zero force.
Instead of using the "Reaction Force" option, the "Free Body Force" option can be used to find out the forces acting on a particular location.
Note that the the free body forces calculated by this tool are dependent on the mesh quality. The higher the mesh quality, the more accurate the results the "Free Body Force" will show.
If you’re still having trouble listing the resultant forces, feel free to call Hawk Ridge Systems Technical Support at 877.266.4469 (US) or 866.587.6803 (Canada) or you can email us at support@hawkridgesys.com.

I've seen a few situations where incompatible mesh resulted with inaccurate Result Forces. My suggestion to change this helped to resolve the issue with these situations
