.Annex60.Fluid.FMI.Interfaces.MassFractionConnector .Annex60.Fluid.FMI.Interfaces.MassFractionConnectorConnector with variable of type
Modelica.SIunits.MassFraction. Note that the mass
fraction is in kg water vapor per total mass of air, rathern than
per kg of dry air.
This connector has been implemented to conditionally remove the mass fraction if the medium has only one species. While this could have been done using a vector of mass fractions with zero length, as is used in fluid connectors, this implemantation uses a scalar to avoid vectorized inputs and outputs of FMUs.
