Perform frequency packing

This example creates a result probe that performs frequency packing, which creates a new occurrence at the central frequency of each frequency band. It outputs the results as a post view.

The model is a vibro-acoustic model of an engine.

The frequency values in the results are:

Create result variable to define displacement in the x direction

• Choose Result Variables and create a result variable to define displacement in the x direction.Name = dxResult Type = DisplacementLocation = NodalOK

Perform frequency packing

1. Choose Result Probe and create the result probe to perform frequency packing. Use the dx variable to define the formula.Name = Frequency PackingFormula = dxLoadcase Selection = AllIteration Type = Frequency Interpolation Option = Real and ImaginaryFrequency Packing Frequency Band = Octave Combine Value of Bands = Arithmetic Mean Selection Type = Entire Model

2. Generate output as a post view.Output Options = Post ViewCreate Output OKThe following shows the frequency 125.000 Hz for imaginary values.The Edit Post View dialog box lists the band central frequency values the frequency packing created.
