Activating FMU Co-Simulation Models

For co-simulation with FMU, you require two physics continua—one continuum for the physics that are solved in Simcenter STAR-CCM+ (the internal continuum) and one continuum that represents the physics in the FMU model (the external continuum).

The initial simulation contains a predefined physics continuum for the physics in Simcenter STAR-CCM+ that models the air flow as an unsteady turbulent fluid.

To enable co-simulation with FMU, add the required co-simulation models:

For the physics continuum, Continua > Fluid, activate the following physics models:


Group	Physics Model
Optional Models	Co-Simulation
Co-Simulation Models	FMI

Select the Continua > Fluid > Initial Conditions > Static Temperature node and set Value to 313 K.

To represent the external physics:

Create a new physics continuum named FMU. For this continuum, select the following models:


Group box	Model
Optional Models	External Continuum
External Continuum	External Application (selected automatically)
Space	Network Topology
External Application	FMI
Time	Implicit Unsteady

Right-click the Regions node and select New > Region.
Select the Regions > Region 1 node and set Physics Continuum to FMU.
Rename Region 1 to FMU.

When you activate the External Continuum model, Simcenter STAR-CCM+ adds a link node under the External Links node. A link represents the connection to an external application and allows you to define the details of the co-simulation.

Using the default link node, specify the external continuum that represents the FMU model, and define the time interval between data transfer events:

Expand the External Links > Link 1 > Conditions node and set the following properties:


Node	Property	Setting
External Continua	Continua	FMU
Coupling Negotiation Option	Option	Time-Step This setting sets the time interval between data exchanges to the simulation time-step.

Later, you also specify the values that are exchanged with the FMU model. For co-simulation with FMU, Simcenter STAR-CCM+ automatically specifies the relevant launch and connect settings.

Save the simulation.
