Parameter

Values

Description

FFRS

<YES, NO>

Defaults:

1.If the parameter is not present in the model, the default is NO.
2.If the parameter is present in the model with no values specified, the run will terminate with an error.

This parameter is used to activate the external FastFRS (Fast Frequency Response Solver). This solver is very efficient for a certain class of large modal frequency response problems, such as those common in automotive NVH analysis. Note that FastFRS must be installed on the system and the environment variable FASTFRS_EXE must point to the FastFRS executable for this parameter to work.

If YES, the external FastFRS solver is used.

If NO, the internal solver is used.

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