HFREQFL

<Real>
(Hertz)

Default = None

Default

If PARAM, HFREQFL is input without specifying a value, the solution runs into an error.

Modes with frequencies greater than HFREQFL are not used in Coupled Modal Frequency Response Analysis. HFREQFL can be used to remove Rigid Body Modes from the Modal Space.

Note: Modes that are eliminated by PARAM, HFREQFL will display an “H” next to the mode number.
