TwoPGridAdaptIndicator()

template<class TypeTag >

Dumux::TwoPGridAdaptIndicator< TypeTag >::TwoPGridAdaptIndicator ( std::shared_ptr< const GridGeometry >  gridGeometry, const std::string &  paramGroup = ""  )

inline

The Constructor.

Parameters

gridGeometry	The finite volume grid geometry
paramGroup	The parameter group in which to look for runtime parameters first (default is "")

Note: refineBound_, coarsenBound_ & maxSaturationDelta_ are chosen in a way such that the indicator returns false for all elements before having been calculated.

Member Function Documentation

calculate()

template<class TypeTag >

void Dumux::TwoPGridAdaptIndicator< TypeTag >::calculate ( const SolutionVector &  sol, Scalar  refineTol = 0.05, Scalar  coarsenTol = 0.001  )

inline

Calculates the indicator used for refinement/coarsening for each grid cell.

Parameters

sol	The solution vector
refineTol	The refinement tolerance
coarsenTol	The coarsening tolerance

This standard two-phase indicator is based on the saturation gradient.

Reset the indicator to a state that returns false for all elements

maxLevel_ must be higher than minLevel_ to allow for refinement

Check for inadmissible tolerance combination

Variables to hold the max/mon saturation values on the leaf

Calculate minimum and maximum saturation

Index of the current leaf-element

Obtain the saturation at the center of the element

Maybe update the global minimum/maximum

Calculate maximum delta in saturation for this cell

Only consider internal intersections

Access neighbor

Visit intersection only once

Obtain saturation in the neighbor

Compute the maximum delta in saturation

Compute the refinement/coarsening bounds

check if neighbors have to be refined too

operator()()

template<class TypeTag >

int Dumux::TwoPGridAdaptIndicator< TypeTag >::operator() ( const Element &  element ) const

inline

function call operator to return mark

Returns

1 if an element should be refined -1 if an element should be coarsened 0 otherwise

Parameters

element

A grid element

setLevels()

template<class TypeTag >

void Dumux::TwoPGridAdaptIndicator< TypeTag >::setLevels ( std::size_t  minLevel, std::size_t  maxLevel  )

inline

Function to set the minimum/maximum allowed levels.

Parameters

minLevel	The minimum level
maxLevel	The maximum level

setMaxLevel()

template<class TypeTag >

void Dumux::TwoPGridAdaptIndicator< TypeTag >::setMaxLevel ( std::size_t  maxLevel )

inline

Function to set the maximum allowed level.

Parameters

maxLevel

The maximum level

setMinLevel()

template<class TypeTag >

void Dumux::TwoPGridAdaptIndicator< TypeTag >::setMinLevel ( std::size_t  minLevel )

inline

Function to set the minimum allowed level.

Parameters

minLevel

The minimum level
