22.2.3 Specifying Acoustic Receivers

In the Acoustics Model dialog box, click the Define Receivers... button to open the Acoustic Receivers dialog box (Figure  22.2.7).

Note that you can also open the Acoustic Receivers dialog box by clicking the Receivers... button in the Acoustic Sources or the Acoustic Signals dialog box.

Increase the Number of Receivers to the total number of receivers for which you want to compute sound, and enter the coordinates for each receiver in the X-Coord., Y-Coord., and Z-Coord. fields. Note that because ANSYS FLUENT's acoustics model is ideally suited for far-field noise prediction, the receiver locations you define should be at a reasonable distance from the sources of sound (i.e., the selected source surfaces). The receiver locations can also fall outside of the computational domain.

For each receiver, you can specify a file name in the Signal File Name field. These files will be used to store the sound pressure signals at the corresponding receivers. By default, the files will be named receiver-1.ard, receiver-2.ard, etc.

Once the receiver locations have been defined, the setup for your acoustic calculation is complete.
