Add a Coupling Interface

Add a coupling interface to the co-simulation.

  1. 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 the interface's Side branch, 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.

  2. Set details for the fluid side of the interface, One.

    1. Set the Coupling Participant to Fluid Flow (Fluent).

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

  3. Set details for the structural side of the interface, Two.

    1. Set the Coupling Participant to MAPDL Transient.

    2. For the Region List setting, select FSIN_1_System Coupling Region.
