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.

Refer to FastFRS Usage (Fast Frequency Response Solver) in the User's Guide for more details.
