Two-dimensional interfaces.

Instances of class Interface represent reacting 2D interfaces

between bulk 3D phases. Class Interface defines no methods of its

own. All of its methods derive from either SurfacePhase or Kinetics.

Function importInterface should usually be used to build an
|
|
Interface object from a CTI file definition, rather than calling
|
|
the Interface constructor directly.
