Compute acoustic power on AML radiation surfaces

1. Choose Home tab → Properties group → Modeling Objects .Alternatively, click Create Modeling Object  in the Case Control page of the acoustic or vibro-acoustic Solution dialog box.

2. In the Modeling Objects Manager dialog box, from the Type list, select Acoustic Output Requests or Vibro-Acoustic Output Requests.

3. Click Create.

4. Click the Acoustic Power page.

5. Select the Enable ACPOWER Request check box.

6. Select the appropriate Output Medium, Data Format, and other options that further define the output.For more information, see Acoustic Output Requests and Vibro-Acoustic Output Requests dialog boxes (Simcenter Nastran).

7. Select the Compute Acoustic Power on Automatically Matched Layer Radiation Surfaces check box to compute the acoustic power on the AML radiation surface.

8. (Optional) In the Element Surfaces for Acoustic Power group, from the Group Selection list, select how to specify the AML radiation surfaces from which you want output.To specify the element surfaces for acoustic power either by selecting existing group(s) or by creating new group(s), select Group.To select existing group(s):From the Options group table, select the appropriate group.See Create a group by manually selecting the contents for more details.To create new group(s):From Select Groups, click and select the geometry or FE entity to which the parameters are to be applied.From the Options group table, select the appropriate group.See Create a group by manually selecting the contents for more details.

Add the defined output requests for acoustic power to the solution

1. Right-click the active acoustic or vibro-acoustic solution and choose Edit.

2. In the Case Control page, from the Output Requests list, select the appropriate output requests.

3. Click OK to close the Solution dialog box.
