Add a Coupling Interface

Add a coupling interface to the co-simulation.

  1. On the Messages tab, click the Action Required message indicating that at least one coupling interface is required.

    The Setup branch is highlighted.

    Note:  The steps in this tutorial follow the standard sequence for creating a co-simulation. You may also address Action Required messages in the order they appear on the Messages tab.

  2. Right-click the Setup branch and select Add Coupling Interface.

    The Coupling Interface branch is added to the tree, with Coupling Interface 1 defined beneath it.

    Under Coupling Interface 1 | Side, there are two objects, called One and Two, which represent the sides of the interface. Their settings are shown in the Properties pane.

    Note:  When running a co-simulation based on an exported Workbench setup, do not change the default coupling interface names.

  3. Set the details for side One of the interface.

    1. Verify that Coupling Participant is set to CFX.

    2. For the Region List setting, select wall_deforming , ensuring that no other regions are selected.

  4. Set the details for side Two of the interface.

    1. Verify that Coupling Participant is set to MAPDL Transient.

    2. For the Region List setting, verify that FSIN_1_System Coupling Region is selected, ensuring that no other regions are selected.
