Description

The discretization schemes available in DuMu^x

Modules
	Box FV scheme
	The box method is a collocated finite volume scheme with control volumes centered at grid nodes.
	Cell-centered FV scheme
	Finite volume schemes with degrees of freedom located at grid cell centers.
	CVFE
	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.
	Face-centered staggered FV scheme
	A staggered finite volume scheme with degrees of freedom at cell-centers and facets. In this implementation, momentum control volumes exist.
	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 method
	The finite element method.
	Pore network model discretization
	The pore-network model discretization.
	PQ1 bubble scheme
	Control-volume finite element scheme based on P1/Q1 basis function with enrichment by a bubble function.
