Hi there,
I don't know, where to adress this, so I want describe the problem, and maybe someone knows, where to adress this problem.
It is a problem in MSL not in OM.

The media definition of MSL contains moist air: Modelica.Media.Air.MoistAir
In there one can find the concentration of water (big X) as kg water / kg moist air and the charge (small x) as kg water/kg dry air.
They are both defined as Modelica.SIunits.Massfraction, with min=0, max=1.

This is ok for X but totally wrong for x. The charge x can be min=0 (max=inf), as ther can be a higher humdity than 1kg water / 1 kg dry air.
This leeds to error messages, when x>1, as Modelica checks the type definition.

As there is no SIunit for that, the correct type would be Real.

Does somebody know, where do adress this?
Regards,
Uwe
