Solution Sequence SOL 103 Input Executive Control Include 'cmsefa.v707' Case Control None. Bulk Data None. Output Matrices representing the fraction of the total strain energy contributed by the component modes. Limitations none. Sample Files cmsef1.dat = solution for the modes of the two-headed flyswatter model. For demonstration purposes, the entire model (with the exception of GRID points 1 and 2, which are constrained) is placed into the superelment. When this is done, the component modes of the superelement are identical to the "system" modes at the residual structure, and the alter output verifies this by indicating that 100% of the strain energy in each system mode comes from the associated component mode. Additional Documentation None.
