Connect parameters (configure a Fluid State submodel)

You can connect Parameters so that the value of one parameter can be automatically propagated to another parameter.

The following example illustrates how to create suitable "connections" so that the Fluid Type that the model uses is automatically set based on the Fluid Type used by the upstream model.

Pass the upstream model's Fluid Type to a Fluid State submodel, and subsequently to downstream models

1. Edit or create a new Model Type.

   In this example, the Model Type represents a process equipment, like a valve, containing an input port, an output port, and a "fluid state" submodel so that it links to thermodynamic calculations.

2. Expand the Models section.

3. Drag the FluidState Model Type from the Submodels Library onto the Models section to make it a submodel.

   

4. Expand the Ports section.

5. Add a port with In as the Direction and Submodels.FluidPort as the Type.

6. Add a port with Out as the Direction and Submodels.FluidPort as the Type.

   

7. Expand the Connections section.

   The connections that we add allow the Fluid Type to propagate from the In port to the FluidState submodel and also to the Out port. This allows the Fluid Type to propagate through the simulation based on Canvas connectivity.

8. Add a new connection, set the Type to Parameter, and enter the following From and To parameters:

   • From: Port1.FluidType

   • To: Port2.FluidType

     This connection propagates the value of the FluidType parameter from the input port to the output port.

9. Add another connection, set the Type to Parameter, and enter the following From and To parameters:

   • From: Port1.FluidType

   • To: <Submodel_name>.FluidType

     This connection propagates the value of the FluidType parameter from the input port to the FluidState submodel where it defines what thermodynamic calculations will be used.

     

     You can now add the model to a simulation and the Fluid State submodel uses the Fluid Type of the upstream model.
