Modal Acoustics

The Modal Acoustics system models a structure and the surrounding the fluid medium to determine frequencies and standing wave patterns within a structure.

This system is configured in Ansys Mechanical, using the Mechanical APDL solver to compute the solution.

To work through a Modal Acoustics system:

  1. To add a Modal Acoustics analysis system, drag the system from the Toolbox to the Project Schematic or double-click the system in the Toolbox.

    Once the analysis type is selected, the following prompt displays.

     

    This prompt informs you that you can automatically create a Physics Region (object) in the downstream Mechanical system by selecting physics types in the Setup cell properties. The Acoustics property, as illustrated below, is a read-only property that is always active.

  2. To ensure the prompt is not displayed again, select the Do not show me this again check box.

  3. To close the prompt, click OK.

  4. To load the geometry, right-click the Geometry cell and select Import Geometry from the context menu.

  5. To open the Mechanical application, right-click the Setup cell and select Edit from the context menu or double-click the Setup cell.

  6. In the Mechanical application window, complete your analysis using the application's tools and features.

    See Modal Acoustics Analysis in the Mechanical Acoustic Analysis Guide for more information on conducting this analysis.
