Users need to know reaction forces on locations other than
where restraints are applied. This is typically useful while trying to quickly
validate the output of simulation results. The reaction force will be equal and
opposite to the applied load. It’s only then that user can claim the object
being simulated is in equilibrium. Another use of this feature is finding the
load to create a certain amount of displacement.
To activate this feature, right click on a name of a test
and select properties. Simply check the radio button for Compute Free Body
force. After running a study with this flag on, right-click the Results
folder and select List Free Body Force to list forces that act on faces,
edges, and vertices. The forces can come from contact, external loads,
restrains, or connectors.
