Selecting the Physics Models
The initial simulation includes a physics continuum with preselected physics models. These models account for the liquid that flows across the check valve. For FMU co-simulation with Simcenter Amesim, you require an additional physics continuum that represents the FMU model.
- Right-click the Continua node and select New Physics Continuum.
-
For the physics continuum Physics 2, select the
following models in order:
Group Box Model Optional Models External Continuum External Application (automatically selected) External Application FMI Network Topology (automatically selected) Time Implicit Unsteady - Click Close.
- Right-click and rename Physics 1 to Fluid (Internal).
- Repeat the previous step for Physics 2, renaming it to FMU (External).

To represent the external FMU model in Simcenter STAR-CCM+, you also require an additional region:
- Right-click the Regions node and select .
- Rename Region 1 to External Region.
- Select the External Region node and set Physics Continuum to FMU (External).
- Save the simulation.
