Specific internal energy in PartialSimpleIdealGasMedium

[modelica-trac-importer]

Reported by msielemann on 31 Aug 2011 09:02 UTC
In 8a5a9ff, a modification was made to function specificInternalEnergy of PartialSimpleIdealGasMedium.

redeclare function extends specificInternalEnergy 
  "Return specific internal energy"
  extends Modelica.Icons.Function;
algorithm 
  // u := (cp_const-R_gas)*(state.T-T0);
  u := cp_const*(state.T-T0) - R_gas*state.T;
end specificInternalEnergy;

The change introduces an inconsistency between the offset in specific enthalpy and that in specific internal energy and should be undone.

Next MSL release seems to be a more fitting milestone for this.
