•	Results are supported through the .op2 and .xdb output files.

•	Grid point force results are requested with the GPFORCE output request.

•	Displacement results are requested with the DISPLACEMENT output request.

•	It is recommended practice to output data for only the node set(s) of interest. This procedure reduces the size of the solver results file and helps speed up the FBD extractions. Consider using STRESS=NONE and STRAIN=NONE to further reduce the size of the results file.

•	MPC forces and moments are properly extracted for the following MPC constraint types:

RBE2

RBE3

RigidLink

RJOINT

RROD
