Extracts neutral plane eigenvectors from a modal analysis for the ROM

APDL Command: RMNEVEC method.


This command extracts the eigenvectors at a neutral plane of a model from a modal analysis. The modal analysis must have expanded modes [MXPAND] in order to process the data. Only the first 9 modes are considered. The command requires a node component named “NEUN” to be defined. These nodes represent the nodes at the neutral plane of a structure (in the case of a stress-stiffened structure), or at any plane in the structure (non stress-stiffened case).

This command is only valid in POST1.

Distributed ANSYS Restriction: This command is not supported in Distributed ANSYS.
