bool gridripper::amr1d::regridder::DefaultRegridder::isFlagged

(

int

i

)

[inline, virtual]

Is the specified grid point flagged?

Returns:

true if flagged, false otherwise

Reimplemented from gridripper::amr1d::Regridder.

bool gridripper::amr1d::regridder::DefaultRegridder::isDynamic

(

)

[inline, virtual]

Tests whether mesh refinement is dynamic.

Points can only be flagged in case of dynamic refinement.

Returns:

true if it is dynamic, false otherwise

setFlagged(int, boolean)

setLastRegridTime(int)

Reimplemented from gridripper::amr1d::Regridder.

void gridripper::amr1d::regridder::DefaultRegridder::setFlagged	(	int	i,
		bool	v
	)			[inline, virtual]

Sets flag on a grid point.

Parameters:

	i	point index
	v	true to flag, false to unflag it

Reimplemented from gridripper::amr1d::Regridder.

void gridripper::amr1d::regridder::DefaultRegridder::init

(

int

maxi

)

[inline, virtual]

Initialization.

Parameters:

maxi

grid maximum index

Reimplemented from gridripper::amr1d::Regridder.

void gridripper::amr1d::regridder::DefaultRegridder::checkErrors	(	Integrator *	integrator,
		double	critical
	)			[virtual]

Flag the points where the error is larger than critical.

Parameters:

	integrator	the grid integrator
	critical	the critical error value

Reimplemented from gridripper::amr1d::Regridder.

virtual IntervalList* gridripper::amr1d::regridder::DefaultRegridder::getIntervalList	(	const Grid &	grid,
		tvalarray< Grid * > &	newSubSubgrids,
		int	minl,
		int	maxl,
		int	numvel,
		int	margin,
		int	bufzoneradius,
		int	tsc
	)			[virtual]

Generates a list of new subgrids from the flagged points.

Parameters:

	grid	the grid
	newSubSubgrids
	minl	the minimum level to regrid, larger than or equal to zero and smaller than Integer.MAX_VALUE if the grids are regenerated, Integer.MAX_VALUE at the first generation
	maxl	the maximum allowed refinement level
	numvel	the error propagation velocity
	margin	margin for new grids
	bufzoneradius	size of the buffer zone
	tsc	time step count

Returns:

the list of intervals to refine

Implements gridripper::amr1d::Regridder.

bool gridripper::amr1d::regridder::DefaultRegridder::hasUncoveredFlaggedPoint	(	const Grid &	grid,
		const tvalarray< Grid * > &	subGrids,
		int	margin
	)			[protected, virtual]

Checks if there exists any flagged point which is not covered by a refined subgrid.

Returns:

true if there are such flagged points, false otherwise

Implements gridripper::amr1d::Regridder.
