PARAM, HFREQFL

Bulk Data Entry Excludes modes with frequencies greater than HFREQFL in Coupled Modal Frequency Response Analysis (Acoustic Analysis).

Parameter	Values	Description
`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.

Description

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.

Comments

Modes that are eliminated by PARAM, HFREQFL will display an "H" next to the mode number.
