Description

Modules

 Cell-centered Finite Volume Methods
 Finite volume schemes with degrees of freedom located at grid cell centers.
 
 Control-volume Finite Element Methods
 Control-volume finite element schemes (e.g. box method) Control-volume finite element schemes are based on finite element basis functions for interpolation but define control volumes to construct a finite volume scheme. They can be interpreted both as finite volume or as (Petrov-Galerkin) finite element scheme.
 
 Staggered Grid Finite Volume Method
 Discretization for the momentum balance of the Navier-Stokes equations. Can be used to build a marker-and-cell scheme (MAC) together with Tpfa for the discretization of the mass balance equation.
 
 Staggered FV scheme
 A staggered finite volume scheme with degrees of freedom at cell-centers and facets. In this implementation, momentum control volumes do not explicitly exist, but the implementation uses workarounds.
 
 Finite Element Methods
 The finite element method.
 
 Pore-network Models
 The pore-network model discretization.
