33.3.32 Acoustic Sources Dialog Box

The Acoustic Sources dialog box allows you to specify the acoustics sources. See Section  22.2 for details about the items below.

Controls

Source Zones   contains a list of zones from which you can select one or more emission (source) surfaces.

Type   contains a list of all possible types of zones from which you can select one or more types of the available zones. If you select an available type of zone, the relevant zones will then be selected in the Source Zones list. If you specify any valid interior zones as source surfaces, the Interior Cell Zone Selection dialog box will appear.

Source Data Root File Name   is used to give the names of the source data files (e.g., acoustic_example_xxxx.asd, where xxxx is the global time-step index of the transient solution) and an index file (e.g., acoustic_example.index) that will store the information associated with the source data.

Write Frequency   allows you to control how often the source data will be written. This will enable you to save disk space if the time-step size used in the transient flow simulation is smaller than necessary to resolve the sound frequency you are attempting to predict.

Number of Time Steps per File   allows you to write the source data to multiple files, each containing the source data for a number of time steps specified by you.

Receivers...   opens the Acoustic Receivers dialog box, which allows you to specify the location of the receivers.
