Create a Model Type that uses multiple Fluid Types in a single model instance

Edit the Model Type to which you want to add multi-component thermodynamics.

Expand the Parameters section.

Add a new parameter, select the Type list, and select Fluid Type.

Name the Parameter; for example, Hot.

Add another Parameter, select the Type list, and select Fluid Type.

Name the Parameter; for example, Cold.

Add the Model Type to your simulation.

Right-click the model instance on the Canvas and select Full Properties to display the Properties Inspector.

Expand the Parameters section.

Beside each parameter, select the Value dropdown menu, expand Fluids and select a Fluid Type.

In the Model Editor, expand the Variables section.

Add a new variable.

Name the Variable; for example, Z.

In the Type list, select a Variable Type.

In the Dim list, select the appropriate components list (CompList) for each parameter you created; for example, Hot.CompList. This defines Z as an array variable of the Hot.CompList dimension.

The CompList for a Fluid Type is built in the Fluid Editor.
