) is used to model mass transport to or from vapor mixtures in contact with liquids. The vapor transfer to or from water or any liquid mixture present on boundaries or in adjacent domains can be studied. The physics interface is the same as the Transport of Concentrated Species interface, but it includes three features for vapor transfer from liquids; Vapor Inflow, Vapor–Liquid Interface, and Vapor–Liquid-Mixture Interface. The first two features are added by default in the interface. All other features for transport and reactions in the Transport of Concentrated Species interface are also always available.
