In the Interface Editor every powertport (Iconic Diagram or Bond Graph) can be assigned a physical domain. 20-sim will use this information to prevent that ports of different physical domains may be connected. More popular: in this way you can never connect a translation model to an electric component.
Use the Interface Editor to assign a physical domain to a port.
In the Interface Editor you can select the physical domain that you want to assign to a port. The editor will show the corresponding port variables and the notation that should be used in the model equations.
The tables below show the available domains and their respective port variables.

For the power domains the variables multiply to power. There are also some domains defined where the variables do not multiply to power. These are called pseudo domains. The following pseudo domains are defined.

You can enter new (pseudo) domains in the Domains, Quantities and Units Editor. If the port is defined as a bond graph port, effort and flow are used to indicate the domain variables. The corresponding tables are shown below.
