Driving point residue (DPR) calculation gives information on optimum point for excitation With test excitation point location, a very important step in the experimental modal analysis process directly affecting PreTest allows prediction and optimization of the sensor locations (accelerometers) for measurements and directions along The MAC utility's Display tab allows you to filter MAC results and select various plotting options using the MAC and COMAC The MAC utility's Load tab allows you to select and load the reference and correlation files and define the model files Modal Assurance Criterion (MAC) is a measure of the correlation between two vibration shapes.

The Model Correlation utility determines the degree of similarity or correlation between two sets of results. 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.Ĭalculate a frequency response based on modal results. Identifies the complex contribution of the excited structure through attachment points to a response in the respondingĭesign sensitivity represents a change in response with respect to a change in a design variable, which is typically Visualize the distribution of energy within a full vehicle NVH model, as a way to understand what components are dominating The Grid Participation utility allows you to plot panel grid participation results and then use advanced scaling contourĬapabilities to isolate key contributing areas.
