Fixed variables

Fixed variables

This is something of a contradiction! They are fixed in the sense that during a simulation they do not change their value. They are variables in the sense that they are exchanged at ports like any other variable. An example is the hydraulic tank or reservoir submodel TK000 which has a fixed variable representing the pressure in the tank.

As with real parameters, you have access to an Expression editor.
