Writes eigenvectors of fluid nodes to a file for use in damping

APDL Command: RMFLVEC parameter extraction.


RMFLVEC extracts the modal information from the modal results file for all nodes specified in a node component called ‘FLUN’. This component should include all nodes which are located at the fluid-structural interface. Mode shapes, element normal orientation, and a scaling factor are computed and stored in a file Jobname.EFL. For damping parameter extraction, use the DMPEXT command macro. See Introduction for more information on thin film analyses.

FLUID136 and FLUID138 are used to model the fluid interface. Both the structural and fluid element types must be active. The fluid interface nodes must be grouped into a component ‘FLUN’. A results file of the last modal analysis must be available.
