16 Perform Far-Field Postprocessing © 2011 ANSYS, Inc. November 22, 2011 The directivity plot at 1 meter (beyond mesh domain) is shown below One can determine how focused the acoustic signal is from this plot, which can help evaluate speaker performance. New in 14.0!
17 Perform Frequency Sweep © 2011 ANSYS, Inc. November 22, 2011 While a frequency sweep can be specified within a Harmonic Response analysis, one can also use Workbench Parameters to specify the sweep Note that “Frequency” is a Workbench Parameter. The frequency for the analysis is made as a parameter equal to this value. The benefit to this approach is that users can add frequencies to the solution after solving without having the re-solve the entire frequency range
