Residual Vectors dialog box (Nastran)

This modeling object lets you control the output of residual vectors and corresponds to the RESVEC case control command.

Note:

Simcenter Nastran only outputs shell thickness results for large strain analyses (PARAM, LGSTRN, 1). To set this parameter in Pre/Post, select the Large Strains (LGSTRN) check box on the Parameters page of the Solution dialog box.

See the Parameter Applicability Tables in the Simcenter Nastran Quick Reference Guide for solutions that support this parameter.
