PARAM, FFRS

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

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 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
