PARAM, LFREQFL

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

Parameter	Values	Description
`LFREQFL`	<Real> (Hertz) Default = None Defaults: If PARAM, `LFREQFL` is input without specifying a value, the solution runs into an error.	Modes with frequencies less than `LFREQFL` are not used in Coupled Modal Frequency Response Analysis. `LFREQFL` can be used to remove Rigid Body Modes from the Modal Space.

Description

LFREQFL

<Real> (Hertz)

Default = None

Defaults:

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

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

Comments

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