Invalid replaceable package

[maltelenz]

There are incompatible classes here:

VirtualFCS/VirtualFCS/SubSystems/Hydrogen/SubSystemHydrogen.mo

Line 7 in df1aa5a

replaceable package Anode_Medium = Modelica.Media.IdealGases.SingleGases.H2(Temperature(start = system.T_start), AbsolutePressure(start = system.p_start)) constrainedby Modelica.Media.Interfaces.PartialSimpleIdealGasMedium;

Message from Wolfram System Modeler:

Error: VirtualFCS.SubSystems.Hydrogen.SubSystemHydrogen [5:15-5:15] Incompatible classes. .Modelica.Media.IdealGases.SingleGases.H2 is not a subtype of .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium, the constraint was imposed here. The following elements are missing or have incompatible types themselves:
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.MolarMass MM_const;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.SpecificHeatCapacity R_gas;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.Temperature T0;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.Temperature T_max;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.Temperature T_min;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.SpecificHeatCapacity cp_const;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.SpecificHeatCapacity cv_const;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.DynamicViscosity eta_const;
  .Modelica.Media.Interfaces.PartialSimpleIdealGasMedium.ThermalConductivity lambda_const;

The here mentioned in the message is the constrainedby from the code linked above.
