The Grid Participation utility allows you to plot panel grid participation results and then use advanced scaling contour
capabilities to isolate key contributing areas.
Generates and post-processes engine order related data from an OptiStruct or Nastran frequency response analysis that contains either RPM-based loading subcases or order-based loading subcases.
PreTest allows prediction and optimization of the sensor locations (accelerometers) for measurements and directions along
with test excitation point location, a very important step in the experimental modal analysis process directly affecting
the accuracy of test results. Driving point residue (DPR) calculation gives information on optimum point for excitation
location.
Frequency Response Assurance Criterion (FRAC) is a measure of the correlation between two frequency response functions
(FRFs) representing the same input-output relationship.
The General Signal Processing utility processes the time domain pressure results from CFD simulations and visualizes
the results in both the time and frequency domain.
Predicts powertrain rigid body mode frequencies and kinetic energy distribution, which play a critical role in optimizing
the mount stiffness and layout configuration, by decoupling powertrain rigid body modes and reducing vibration transmission.
Reads results from an OptiStruct optimization run and processes the results to review the overlay of the NVH responses, baseline versus optimized.
Compare changes in the design variable values, baseline versus optimized.
The Model Correlation utility determines the degree of similarity or correlation
between two sets of results.
Modal Assurance Criterion (MAC)
Modal Assurance Criterion (MAC) is a measure of the correlation between two vibration shapes.
