The Coupled Field Modal system models a structure and the surrounding the fluid medium to determine frequencies and standing wave patterns within a structure. The system supports 2D coupled, structural acoustics, and structural electric physics.
This system is configured in Ansys Mechanical, using the Mechanical APDL solver to compute the solution.
To work through a Coupled Field Modal system:
To add a Coupled Field Modal 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. Both the Structural, Acoustics, and Electric properties, as illustrated below, are read-only properties that are always active. The Acoustics property is also read-only and is off by default.

To ensure the prompt is not displayed again, select the Do not show me this again check box.
To close the prompt, click .
To load the geometry, right-click the Geometry cell and select from the context menu.
To import the model, double-click the Setup cell or right-click the Setup cell and select from the context menu.
In the Mechanical application window, complete your analysis using the application's tools and features.
