PARAM, FFRSLFREQ

Bulk Data Entry Defines a frequency cut-off value in Hertz used to partition the structural system into low frequency and high frequency parts.

Parameter	Values	Description
`FFRSLFREQ`	<Real> Default = 1.0	PARAM, `FFRSLFREQ` relates to the FastFRS interface. It defines a frequency cut-off value in Hertz used to partition the structural system into low frequency and high frequency parts, to improve matrix condition numbers and solution accuracy at a very small computational cost. If the value is defined as 0.0, then FastFRS will set `FFRSLFREQ` to 1.0. For more details, refer to FastFRS (Fast Frequency Response Solver) in the User Guide.
