PARAM, FFRSNCPU

Bulk Data Entry Defines the number of CPUs to be used by the external FastFRS solver.

Parameter Values Description
FFRSNCPU <Integer>

Default = number of cpu's used by OptiStruct

 PARAM, FFRSNCPU relates to the FastFRS interface.

This parameter is used to define the number of CPUs to be used by the external FastFRS solver. This parameter will set the environment variable OMP_NUM_THREADS. The default value is the current value of OMP_NUM_THREADS.

For more details, refer to FastFRS (Fast Frequency Response Solver) in the User Guide.

Comments

  1. If FFRSNCPU is not set, but AMLSNCPU is set, the FastFRS will use the number of CPUs specified by AMLSNCPU.
  2. OptiStruct and FastFRS can be run with different allocations of processors. For example, OptiStruct can be run with one processor and FastFRS with four processors in the same run.
  3. This parameter is only valid when PARAM, FFRS or the run option -ffrs is set to YES.
