In the Moist Air default subfeature of Moist Porous Medium, the Absolute pressure, pA (Model Input section) and the Velocity field, ug (Heat Convection section) are automatically set to the variables from the Nonisothermal Flow multiphysics coupling feature. In the Thermodynamics, Moist Air section, the Input quantity is set to Relative humidity, and the Relative humidity, , the Relative humidity, temperature condition, , and the Relative humidity, absolute pressure condition, , are automatically set to the variables from the Heat and Moisture multiphysics coupling feature.
In the Liquid Water Properties section of the Liquid Water default subfeature of Moist Porous Medium, the Liquid water saturation, sl, and the Velocity field, liquid water, ul, are automatically set to the variables from the Heat and Moisture multiphysics coupling feature.
The latent heat sources are automatically handled on boundaries where Wet Surface or Moist Surface features are applied.

In the Hygroscopic Porous Medium default domain feature, the Absolute pressure, pA (Model Input section) and the Velocity field, ug (Moist Air Properties section) are automatically set to the variables from the Moisture Flow multiphysics coupling feature. In the Model Input section, the Temperature, T, is automatically set to the variable from the Heat and Moisture multiphysics coupling feature.

In the Fluid and Matrix Properties default domain feature, the Temperature, T, and the Density, ρ, are set to the variables from the Nonisothermal Flow multiphysics coupling feature, and the Dynamic viscosity, μ, is set to the variable from the Moisture Flow multiphysics coupling feature. Note that the density and viscosity are those of the moist air phase.
