◆ addPointSources()

template<class TypeTag >

void Dumux::FVProblem< TypeTag >::addPointSources ( std::vector< PointSource > & pointSources ) const

inline

Parameters

pointSources A vector of PointSource s that contain source values for all phases and space positions.

For this method, the values method of the point source has to return the absolute rate values in units \( [ \textnormal{unit of conserved quantity} / s ] \). Positive values mean that the conserved quantity is created, negative ones mean that it vanishes. E.g. for the mass balance that would be a mass rate in \( [ kg / s ] \).

template<class TypeTag >

static constexpr bool Dumux::FVProblem< TypeTag >::enableInternalDirichletConstraints ( )

inlinestaticconstexpr

std::bitset<N> hasInternalDirichletConstraint(const Element& element, const SubControlVolume& scv) const;

where N is the number of equations and where the return value defines for each equation if the corresponding dof associated with the element/scv pair is constraint. If true is returned for a dof, the assembler calls problem.internalDirichlet(element, scv). This means you have to additionally implement the following member function

which returns the enforced Dirichlet values the dof associated with the element/scv pair.

For this method, the return parameter stores the conserved quantity rate generated or annihilate per volume unit. Positive values mean that the conserved quantity is created, negative ones mean that it vanishes. E.g. for the mass balance that would be a mass rate in \( [ kg / (m^3 \cdot s)] \).
