rmmrange

Mapdl.rmmrange(mode='', key='', min_='', max_='', nstep='', damp='', scale='', **kwargs)

Defines and edits various modal parameters for the ROM method.

APDL Command: RMMRANGE

Parameters
mode

Mode number. Must be lower or equal to the number of modes extracted via the RMNEVEC command.

key

Mode classification key. Valid keys are:

DOMINANT - Dominant mode

min_

Lower bound for fit range of mode.

max_

Upper bound for fit range of mode.

nstep

Number of equidistant steps in fit range of mode.

damp

Modal damping factor. Defaults to 0.0.

scale

Modal scaling factor.

Notes

When selected manually (RMMSELECT), modes must be classified as dominant, relevant, or unused. Dominant modes (Key = DOMINANT) are basis functions with large amplitudes. Relevant modes (Key = RELEVANT) are influenced by the dominant modes but do not cause interactions among themselves due to the small amplitude. This assumption leads to essential speed up of the sample point generator (see RMSMPLE).
