A pragmatic method is presented for solving finite element models (FEMs) using MSC/NASTRAN superelement solution 101 and solution 103 capabilities. Sample case control and setups are provided that have been successfully tested with Space Station Freedom FEM models involving approximately 50,000 degrees of freedom (DOF) and several superelements. Use of translational and rotational accelerations at the system center of gravity for linear static analysis using solution 101 is illustrated. The superelement capability permitted an effective team effort where members of the team investigated and optimized the design of their components/superelements in parallel to reduce design cycle time. The recovery of residual interface loads is also discussed.
