This chapter describes the physics interfaces found under the
Chemical Species Transport branch (

). It summarizes the physics interfaces including the different fields, material properties, and boundary conditions associated with them, and suggests how and when to apply the conditions.
The Moisture Flow Interface as well as
The Reacting Flow in Porous Media Interface are also available under the
Chemical Species Transport branch. They are described in the chapter
Multiphysics Interfaces and Couplings.
