Other Listings You can list other types of results with the following commands: The PRVECT command (Main Menu> General Postproc> List Results> Vector Data) lists the magnitude and direction cosines of specified vector quantities for all selected elements. The PRPATH command (Main Menu> General Postproc> List Results> Path Items) calculates and then lists specified data along a predefined geometry path in the model. You must define the path and map the data onto the path; see Mapping Results onto a Path (p. 155). The PRSECT command (Main Menu> General Postproc> List Results> Linearized Strs) calculates and then lists linearized stresses along a predefined path. The PRERR command (Main Menu> General Postproc> List Results> Percent Error) lists the percent error in energy norm for all selected elements. The PRITER command (Main Menu> General Postproc> List Results> Iteration Summry) lists iteration summary data. The PRENERGY command lists the energies of the entire model or the energies of the specified components. Release 13.0 - © SAS IP, Inc.
