The Phase Transport in Free and Porous Media Flow Interface
The Phase Transport in Free and Porous Media Flow interface (), found under the Fluid Flow > Multiphase Flow > Phase Transport branch (), is used to simulate the transport of multiple phases both in free flow and in flow through a porous medium. The interface is the same as the Phase Transport interface but it uses other defaults: both a Fluid and a Porous Medium node are added by default. In addition a default Free-Porous Interface boundary condition is added.
The Phase Transport in Free and Porous Media Flow interface can be used for stationary and time-dependent analyses.
The main features are:
•
The Fluid node, which provides a user interface for defining the phase material along with the transporting flow properties.
•
The Porous Medium node, which provides a user interface for defining the phase materials along with the transporting porous medium flow properties.
•
The Free-Porous Interface node, which provides a user interface for defining the interfacial condition applied at the free-porous interface.
When this physics interface is added, the following default nodes are also added in the Model Builder — Fluid, Porous Medium, No Flux (the default boundary condition), Free-Porous Interface, and Initial Values. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions and mass sources. You can also right-click the Phase Transport in Free and Porous Media Flow node to select physics features from the context menu.

The rest of the settings are the same as for the Phase Transport interface.
