Frequency Response Assurance Criterion (FRAC)

Frequency Response Assurance Criterion (FRAC) is a measure of the correlation between two frequency response functions (FRFs) representing the same input-output relationship.

Supported vibration shapes include:

The frequency response results are assumed to come in one of the following result files:

H3D – binary result file typically generated using OptiStruct.
OP2 – binary result file typically generated using OptiStruct or Nastran.
PCH - ASCII result file typically generated using OptiStruct or Nastran.
UNV – ASCII result file typically exported from testing software.
