## Detailed Description

template<class EffLawT, class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
class Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >

This material law takes a material law defined for unscaled saturation and converts it to a material law defined on scaled saturations.

In ECL, simulations "live" in scaled space, while the saturation functions operate on and produce unscaled quantities. This class implements the "impedance adaption" layer between the two worlds. The basic purpose of it is thus the same as the one of EffToAbsLaw, but it is quite a bit more complex.

## Member Function Documentation

## capillaryPressures()

template<class EffLawT , class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
template<class Container , class FluidState >

static void Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >::capillaryPressures | ( | Container & | ,
|  | const Params & | ,
|  | const FluidState & |
| ) |  |

inline static

The capillary pressure-saturation curves depending on absolute saturations.

Parameters

  values | A random access container which stores the relative pressure of each fluid phase.
  params | The parameter object expressing the coefficients required by the van Genuchten law.
  fs | The fluid state for which the capillary pressure ought to be calculated

## krw()

template<class EffLawT , class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
template<class FluidState , class Evaluation = typename FluidState::Scalar>

static Evaluation Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >::krw | ( | const Params & | ,
|  | const FluidState & |
| ) |  |

inline static

The relative permeability for the wetting phase.

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
  Relative permeability of the wetting phase calculated as implied by EffLaw e.g. Brooks & Corey, van Genuchten, linear... .

## pcnw()

template<class EffLawT , class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
template<class FluidState , class Evaluation = typename FluidState::Scalar>

static Evaluation Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >::pcnw | ( | const Params & | ,
|  | const FluidState & |
| ) |  |

inline static

The capillary pressure-saturation curve.

Parameters

  params | A object that stores the appropriate coefficients for the respective law.

Returns
  Capillary pressure [Pa] calculated by specific constitutive relation (e.g. Brooks & Corey, van Genuchten, linear...)

## relativePermeabilities()

template<class EffLawT , class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
template<class Container , class FluidState >

static void Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >::relativePermeabilities | ( | Container & | ,
|  | const Params & | ,
|  | const FluidState & |
| ) |  |

inline static

The relative permeability-saturation curves depending on absolute saturations.

Parameters

  values | A random access container which stores the relative permeability of each fluid phase.
  params | The parameter object expressing the coefficients required by the van Genuchten law.
  fs | The fluid state for which the relative permeabilities ought to be calculated

## scaledToUnscaledSatPc()

template<class EffLawT , class ParamsT = EclEpsTwoPhaseLawParams<EffLawT>>
template<class Evaluation >

static Evaluation Opm::EclEpsTwoPhaseLaw< EffLawT, ParamsT >::scaledToUnscaledSatPc | ( | const Params & | params,
|  | const Evaluation & | SwScaled
| ) |  |

inline static

Convert an absolute saturation to an effective one for capillary pressure.

The effective saturation is then feed into the "raw" capillary pressure law.
