# 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.
