Connect ports in a Model Type

You can connect two ports within a Model Type by using a port connection. When you connect two ports, all the variables and parameters in one port are connected to the corresponding variables and parameters in the other port as a set of variable and parameter connections.

When you add a port connection in the Model Editor, both ports must be of the same Port Type or a red bad status indicator will appear next to the connection.

You can iterate over port connections in a Model Type that contains a series of submodels of the same type. For example, the following Pipe (from the Pipe in the optional Transient Flow library) contains an N number of Wall and Flow submodels with ports that connect by using the following iterative port connections.

Normally, the Model Editor does not allow you to create two port connections with the same definition (that is, the same From and To ports). However, the Model Editor allows you to do this if you specify a condition for the identical port connections.

Connect two ports

1. Edit or create a new Model Type.

2. Expand the Connections section.

3. Add a new connection and select Port as the Type.

4. Select the Condition, if applicable. See Add a condition to a Model Type for more information.

5. In the From and To column, enter the names of the ports.

6. If the port connection uses an iterator, enter the Start and End values.
