Detailed Description

template<class TypeTag>
class Ewoms::RichardsPrimaryVariables< TypeTag >

Represents the primary variables used in the Richards model.

This class is basically a Dune::FieldVector which can retrieve its contents from an aribitatry fluid state.

template<class TypeTag >

Ewoms::RichardsPrimaryVariables< TypeTag >::RichardsPrimaryVariables ( Scalar  value )

inline

Member Function Documentation

template<class TypeTag >

void Ewoms::RichardsPrimaryVariables< TypeTag >::assignImmiscibleFromNonWetting ( Scalar  T, Scalar  pn, Scalar  Sn, const MaterialLawParams &  matParams  )

inline

Set the primary variables with the non-wetting phase pressure, saturation and temperature.

Parameters

T	The temperature [K]
pn	The pressure of the non-wetting phase [Pa]
Sn	The saturation of the non-wetting phase []
matParams	The capillary pressure law parameters

template<class TypeTag >

void Ewoms::RichardsPrimaryVariables< TypeTag >::assignImmiscibleFromWetting ( Scalar  T, Scalar  pw, Scalar  Sw, const MaterialLawParams &  matParams  )

inline

Set the primary variables with the wetting phase pressure, saturation and temperature.

Parameters

T	The temperature [K]
pw	The pressure of the wetting phase [Pa]
Sw	The saturation of the wetting phase []
matParams	The capillary pressure law parameters

template<class FluidState >

void Ewoms::RichardsPrimaryVariables< TypeTag >::assignMassConservative ( const FluidState &  fluidState, const MaterialLawParams &  matParams, bool  isInEquilibrium = false  )

inline

Set the primary variables from an arbitrary fluid state in a mass conservative way.

If an energy equation is included, the fluid temperatures are the same as the one given in the fluid state, not the enthalpy.

Parameters

fluidState	The fluid state which should be represented by the primary variables. The temperatures, pressures, compositions and densities of all phases must be defined.
matParams	The capillary pressure law parameters
isInEquilibrium	If true, the fluid state expresses thermodynamic equilibrium assuming the relations expressed by the fluid system. This implies that in addition to the quantities mentioned above, the fugacities are also defined.

template<class FluidState >

void Ewoms::RichardsPrimaryVariables< TypeTag >::assignNaive ( const FluidState &  fluidState )

inline

Directly retrieve the primary variables from an arbitrary fluid state.

This method retrieves all primary variables from an abitrary fluid state without careing whether the state which is represented by the resulting primary variables features the equivalent mass as the given fluid state. This method is massively cheaper and simpler than assignMassConservative() but it should be used with care!

Parameters

fluidState

The fluid state which should be represented by the primary variables. The temperatures, pressures, compositions and densities of all phases must be defined.

void Ewoms::FvBasePrimaryVariables< TypeTag >::checkDefined ( ) const

inlineinherited

Instruct valgrind to check the definedness of all attributes of this class.

template<class TypeTag >

Evaluation Ewoms::FvBasePrimaryVariables< TypeTag >::makeEvaluation ( int  varIdx, int  timeIdx  ) const

inlineinherited

Return a primary variable intensive evaluation.

i.e., the result represents the function f = x_i if the time index is zero, else it represents the a constant f = x_i. (the difference is that in the first case, the derivative w.r.t. x_i is 1, while it is 0 in the second case.
