Select an External Terminal feature in the
Source list to define which node of the thermal network provides the heat rate
Pext to be prescribed on the boundary.
When the Isothermal terminal check box is not selected (default), the average temperature on the boundaries is constrained to the temperature at the terminal node of the thermal network. Select this check box to apply the constraint on the space-dependent temperature instead, which corresponds to a stronger constraint.
