Complete the Fluid Setup

The fluid physics are already set up. To complete the Fluid Flow (CFX) system's setup, you need only to create CFX's coupling interface. The coupling interface is where the fluid in the Fluid Flow (CFX)analysis interacts with the plate in the Transient Structural analysis. Data will be exchanged across this interface during the execution of the simulation.

Define this interface on the regions in the fluid-flow model that will receive displacement data from the Transient Structural analysis.

  1. Open the case in CFX-Pre.

    On the Project Schematic, double-click the Fluid Flow (CFX) system's Setup cell.

    CFX-Pre opens in a separate window, with the case loaded.

  2. Create the interface boundary.

    1. Select Insert > Boundary.

      The Insert Boundary dialog opens.

    2. Name the new boundary wall_deforming.

    3. Click OK.

      The Boundary: wall_deforming tab opens.

  3. Verify the following settings on the Basic Settings tab:

    1. Boundary Type is set to Wall.

    2. Location is set to wall_deforming.

  4. On the Boundary Details tab under Mesh Motion, set Option to System Coupling.

  5. Save your settings and close the Boundary: wall_deforming tab.

    Click Apply and then click OK.

  6. Save the project and exit CFX-Pre.

    Select File > Save Project and then File > Close CFX-Pre.

The fluid setup is complete.
