) is used to compute the relative humidity distribution in air. It simulates moisture transport by vapor convection and diffusion in moist air and the evaporation or condensation on walls.
) is used to compute the relative humidity field in porous media. It simulates moisture transport by vapor convection and diffusion in the gas phase, liquid water transport by convection and capillarity in the pores of the media. A Hygroscopic Porous Medium feature is active by default on all domains.
) is used to compute the relative humidity field and liquid water saturation in porous media. It simulates moisture transport by vapor convection and diffusion in the gas phase, liquid water transport by convection and capillarity in the pores of the media. A Hygroscopic Porous Medium feature is active by default on all domains. It differs from simpler macroscale models for moisture transport in porous media where the amount of water in vapor and liquid phases follows the equilibrium condition.
) is used to compute the relative humidity field in building materials. It simulates moisture transport by taking into account moisture storage, liquid transport by capillary suction forces, and convective transport of vapor.
) is used to compute the relative humidity field in all domains, and additionally the liquid water saturation in porous media. It simulates moisture transport by vapor convection and diffusion in the gas phase, liquid water transport by convection and capillarity, in the pores of the media. A Moist Air feature is active by default on all domains, and a Hygroscopic Porous Medium is added by default with no selection. This interface handles all types of interface between free and porous media, and between two porous media.
) is used to compute the relative humidity and moist air pressure in porous media. It simulates moisture transport by vapor convection and diffusion in the gas phase and liquid water transport by convection and capillarity in the pores of the medium. A Porous Medium feature is active by default on all domains. This interface has its own specific features, and formulation of equations, making it different from the other Moisture Transport interfaces.
