Defines and edits various modal parameters for the ROM method.
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 |
RELEVANT | — | Relevant mode |
UNUSED | — | Unused mode. Do not consider mode in ROM. |
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.
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).
