Description

template<class TypeTag, bool adaptive>
class Dumux::GridAdapt< TypeTag, adaptive >

Standard Module for h-adaptive simulations.

This class is created by the problem class with the template parameters <TypeTag, true> and provides basic functionality for adaptive methods:

A standard implementation adaptGrid() will prepare everything to calculate the next pressure field on the new grid.

Member Function Documentation

adaptGrid() [1/2]

template<class TypeTag, bool adaptive>

void Dumux::GridAdapt< TypeTag, adaptive >::adaptGrid ( )

inline

Standard method to adapt the grid.

This method is called from IMPETProblem::preTimeStep() if adaptive grids are used in the simulation. It uses the standard indicator (selected by the property AdaptionIndicator) and forwards to with it to the ultimate method adaptGrid(indicator), which uses a standard procedure for adaptivity: 1) Determine the refinement indicator 2) Mark the elements 3) Store primary variables in a map 4) Adapt the grid, adapt variables sizes, update mappers 5) Reconstruct primary variables, regain secondary variables

adaptGrid() [2/2]

template<class TypeTag, bool adaptive>

template<class Indicator>

void Dumux::GridAdapt< TypeTag, adaptive >::adaptGrid ( Indicator & indicator )

inline

Method to adapt the grid with individual indicator vector.

Parameters

indicator

The refinement indicator that is applied

This method is called by an user-defined preTimeStep() of the applied problem and takes a given vector with indicator values.

It uses a standard procedure for adaptivity: 1) Determine the refinement indicator 2) Mark the elements 3) Store primary variables in a map 4) Adapt the grid, adapt variables sizes, update mappers 5) Reconstruct primary variables, regain secondary variables

adaptionIndicator() [1/2]

template<class TypeTag, bool adaptive>

AdaptionIndicator & Dumux::GridAdapt< TypeTag, adaptive >::adaptionIndicator ( )

inline

adaptionIndicator() [2/2]

template<class TypeTag, bool adaptive>

AdaptionIndicator & Dumux::GridAdapt< TypeTag, adaptive >::adaptionIndicator ( ) const

inline

getMaxLevel()

template<class TypeTag, bool adaptive>

int Dumux::GridAdapt< TypeTag, adaptive >::getMaxLevel ( ) const

inline

Returns maximum refinement level.

The value is the assign maximum possible level, not the actual maximum level of the grid.

Returns

levelMax_ maximum level for refinement

getMinLevel()

template<class TypeTag, bool adaptive>

int Dumux::GridAdapt< TypeTag, adaptive >::getMinLevel ( ) const

inline

Returns minimum refinement level.

The value is the assign minimum possible level, not the actual minimum level of the grid.

Returns

levelMin_ minimum level for coarsening

init()

template<class TypeTag, bool adaptive>

void Dumux::GridAdapt< TypeTag, adaptive >::init ( )

inline

Initalization method of the h-adaptive module.

Prepares the grid for simulation after the initialization of the problem. The applied indicator is selectable via the property AdaptionInitializationIndicator

markElements()

template<class TypeTag, bool adaptive>

template<class Indicator>

void Dumux::GridAdapt< TypeTag, adaptive >::markElements ( Indicator & indicator )

inline

Mark Elements for grid refinement according to applied Indicator

Returns

Total ammount of marked cells

setLevels()

template<class TypeTag, bool adaptive>

void Dumux::GridAdapt< TypeTag, adaptive >::setLevels ( int levMin, int levMax )

inline

Sets minimum and maximum refinement levels

Parameters

levMin	minimum level for coarsening
levMax	maximum level for refinement

wasAdapted()

template<class TypeTag, bool adaptive>

bool Dumux::GridAdapt< TypeTag, adaptive >::wasAdapted ( )

inline

Returns true if grid cells have been marked for adaptation.
