#include <dumux/material/fluidmatrixinteractions/2p/efftoabsdefaultpolicy.hh>

Description

This is a policy for 2p material laws how to convert absolute to relative saturations and vice versa.

Material laws (like VanGenuchten or BrooksCorey) are defined for effective saturations. The numeric calculations however are performed with absolute saturations. The policy class converts the saturations. This allows for changing the calculation of the effective saturations easily, as this is subject of discussion / may be problem specific.

dsw_dswe()

template<class Scalar >

static Scalar Dumux::FluidMatrix::TwoPEffToAbsDefaultPolicy::dsw_dswe ( const Params< Scalar > &  params )

inlinestatic

Derivative of the absolute saturation w.r.t. the effective saturation.

Parameters

params

A container object that is populated with the appropriate coefficients for the respective law. Therefore, in the (problem specific) spatialParameters first, the material law is chosen, and then the params container is constructed accordingly. Afterwards the values are set there, too.

Returns

Derivative of the absolute saturation w.r.t. the effective saturation.

dswe_dsw()

template<class Scalar >

static Scalar Dumux::FluidMatrix::TwoPEffToAbsDefaultPolicy::dswe_dsw ( const Params< Scalar > &  params )

inlinestatic

Derivative of the effective saturation w.r.t. the absolute saturation.

Parameters

params

A container object that is populated with the appropriate coefficients for the respective law. Therefore, in the (problem specific) spatialParameters first, the material law is chosen, and then the params container is constructed accordingly. Afterwards the values are set there, too.

Returns

Derivative of the effective saturation w.r.t. the absolute saturation.

makeParams()

template<class Scalar >

static Params< Scalar > Dumux::FluidMatrix::TwoPEffToAbsDefaultPolicy::makeParams ( const std::string &  paramGroup )

inlinestatic

Construct from a subgroup from the global parameter tree.

Note

This will give you nice error messages if a mandatory parameter is missing

sweToSw()

template<class Scalar >

static Scalar Dumux::FluidMatrix::TwoPEffToAbsDefaultPolicy::sweToSw ( const Scalar  swe, const Params< Scalar > &  params  )

inlinestatic

Convert an effective wetting saturation to an absolute one.

Parameters

swe	Effective saturation of the non-wetting phase \(\mathrm{[\overline{S}_n]}\).
params	A container object that is populated with the appropriate coefficients for the respective law. Therefore, in the (problem specific) spatialParameters first, the material law is chosen, and then the params container is constructed accordingly. Afterwards the values are set there, too.

Returns

Absolute saturation of the non-wetting phase.

swToSwe()

template<class Scalar >

static Scalar Dumux::FluidMatrix::TwoPEffToAbsDefaultPolicy::swToSwe ( const Scalar  sw, const Params< Scalar > &  params  )

inlinestatic

Convert an absolute wetting saturation to an effective one.

Parameters

sw	Absolute saturation of the wetting phase \(\mathrm{[{S}_w]}\).
params	A container object that is populated with the appropriate coefficients for the respective law. Therefore, in the (problem specific) spatialParameters first, the material law is chosen, and then the params container is constructed accordingly. Afterwards the values are set there, too.

Returns

Effective saturation of the wetting phase.
