Conditional component used in an equation

[maltelenz]

Here, partialArc is used in an equation:

ThermoPower/ThermoPower/PowerPlants.mo

Line 13459 in d028b9e

w = Kt*partialArc*sqrt(Medium.pressure(steamState_in)*Medium.density(

It is declared here as a conditional component:

ThermoPower/ThermoPower/Water.mo

Line 6028 in d028b9e

Modelica.Blocks.Interfaces.RealInput partialArc if usePartialArcInput

This is illegal Modelica:

A component declared with a condition-attribute can only be modified and/or used in connections.

Edit: I realize now that it is also part of the abandoned package mentioned here: #17 (comment)
