### 13.1.6. Running CFX as a System Coupling Participant from the Command Line

System Coupling analyses can be run via the command line (described in Executing System Couplings Using the Command Line in the System Coupling User's Guide). To run ANSYS CFX as a coupling participant, execute the following steps:

- Complete the System Coupling-related settings in CFX.

- Generate the Solver Input file needed to start CFX.

- Start the coupling service and obtain the following information from the System Coupling Server (SCS) file:

  - the port and host on which the service is being run

  - the identifier (or name) for CFX, and (optionally)

  - licensing ID and licensing port and host. The command-line options for licensing ID and licensing port and host are described in Command-Line Options and Keywords for cfx5solve in the CFX-Solver Manager User's Guide.
