Steady State or Transient System Coupling.

Parallel/distributed processing of Forte simulations.

Launching System Coupling via either Command-Line Interface (CLI) or Graphical User Interface (GUI).

Performs Conjugate Heat Transfer (CHT) analysis on the boundary condition selected for System Coupling. Heat Transfer Rate (or Heat Transfer Coefficient and Near-wall Temperature) can be provided to other coupling participants, and temperature can be received from them. Here, the heat transfer data refer to those of convective heat transfer.

Performs Fluid Structure Interaction (FSI) on the boundary condition selected for System Coupling. Force can be provided to other coupling participants, and displacement can be received from them.

In a CHT analysis, Forte initializes the data being transferred at the coupled boundaries.

In a FSI analysis, the initialization follows the default system coupling rules.

Forte cannot be added as a System Coupling participant via Ansys Workbench.

To be a participant for System Coupling, Forte must have the System Coupling node (under Simulation Controls) checked (turned ON) with at least one coupled surface selected.

The coupling interface must be a wall boundary condition in Forte.

In Forte, a wall boundary condition that is selected for System Coupling must be associated with one and only one surface patch of the simulation domain.

Steady State System Coupling is limited to CHT Analysis. The output variables from Forte for a Steady State System Coupling (that is, Heat Transfer Rate, or Heat Transfer Coefficient and Near-wall Temperature) are spatially resolved but time-averaged. The time average frequency is controlled by a Monitor Probe's inquiry frequency. If no Monitor Probe is set, the spatially averaged output frequency is used.

Transient System Coupling is available for both CHT Analysis and FSI analysis. In a Transient System Coupling analysis the output variables are spatially resolved and their time averaging is performed over each coupling time step instead of over the entire simulation time.

In a CHT analysis, the heat transfer rate and coefficient are for convective heat transfer only. Radiation effects are not included even if the radiation heat transfer model is turned on.

In principle, you may couple Ansys Forte with any application that is accepted as Ansys System Coupling participant. However, the most common and thoroughly tested use cases are coupling Ansys Forte with Ansys Fluent and/or Ansys Mechanical.

Windows systems have a limit for the length of path strings unless you are using Windows 10 or later and your registry has been modified to allow longer paths. See https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry for more details. If you do not have this modification in the Windows registry, ensure that the path to the .ftsim does not exceed 256 characters. Ansys Forte cannot execute the run if the path exceeds 256 characters on Windows systems.
