PARAM, FFRS

Bulk Data Entry Used to activate the external FastFRS (Fast Frequency Response Solver).

Parameter Values Description

Parameter	Values	Description
`FFRS`	<YES, NO> Defaults: If the parameter is not present in the model, the default is NO. If the parameter is present in the model with no values specified, the run will terminate with an error.	This solver is very efficient for a certain class of large modal frequency response problems, such as those common in automotive NVH analysis. Note: FastFRS must be installed on the system and the environment variable `FASTFRS_EXE` must point to the FastFRS executable for this parameter to work. YES The external FastFRS solver is used. NO The internal solver is used. For more details, refer to FastFRS (Fast Frequency Response Solver) in the User Guide.

<YES, NO>

Defaults:

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

This solver is very efficient for a certain class of large modal frequency response problems, such as those common in automotive NVH analysis.

Note: FastFRS must be installed on the system and the environment variable FASTFRS_EXE must point to the FastFRS executable for this parameter to work.

YES: The external FastFRS solver is used.
NO: The internal solver is used.
