5.6.2. Operation

Only curves plotted in the time domain are available for analysis in Ansys Sound: Analysis and Specification, but multiple curves can be exported at once. Data is interpolated, if necessary, to ensure the same time-step.

To launch the Ansys Sound: Analysis and Specification interface from the Motion Postprocessor:

  1. Select the required curve in Chart view.

  2. Click Ansys Sound on the Analysis ribbon menu.

    This launches the Ansys Sound: Analysis and Specification application.

  3. Select the required signal from the Ansys Sound: Analysis and Specification dialog (see below).
