You may use Ansys software applications that are System Coupling participants in the coupled simulation. Typically, Ansys Fluent or Ansys Mechanical is used as the other participant. In a Conjugate Heat Transfer analysis, Forte is typically used to simulate engine flow and combustion processes, while the other participant should be able to perform thermal analysis in the solid engine walls and receive heat transfer data from Forte. In a Fluid Structure Interaction analysis, Forte is typically used to simulate the force originated from the fluid flow acting on the moving surface/s, while the other participant should be able to provide the structure response (displacement) back to Forte.
In general, the participant's project used for System Coupling is very similar to the one used for its stand-alone application. The difference is that the boundary conditions for the coupling interfaces should be set to use System Coupling.
Certain participants (such as Ansys Fluent and Ansys Mechanical) need to export a System Coupling participant file (.scp) from their projects. These participant files must be placed in the working directory and are used by System Coupling for setup. For detailed information about the format of the .scp file, refer to Participant Setup File in the System Coupling User's Guide .
Ansys Fluent as the Other Participant
For detailed information about setting up Ansys Fluent for System Coupling, refer to Performing System Coupling Simulations Using Fluent in the Fluent User's Guide, in particular, System Coupling Related Settings in Fluent.
The following Forte tutorials provide examples of using Ansys Fluent as the other System Coupling participant:
Ansys Mechanical as the Other Participant
For detailed information about setting up Ansys Mechanical for System Coupling, refer to System Coupling in the Mechanical User's Guide, in particular, System Coupling Related Settings in Mechanical.
The following Forte tutorial provides an example of using Ansys Mechanical as the other System Coupling participant:
Note: After the Fluent or Mechanical project is prepared, it is good practice to run it as a stand-alone project before attempting a System Coupling simulation. This is a sanity check to detect if there is anything wrong or unexpected in the project's setup. You may also know roughly how long it takes to complete such a simulation. To run the Fluent or Mechanical project stand-alone, set the boundary conditions on the supposed coupling interface to presumed ones (e.g., with constants) rather than System Coupling.
