virtual void gridripper::amr1d::FuncInitCond::endInit ( ) [inline, protected, virtual]

Called at the end of init.

This method can free temporarily allocated memory or perform other clean-up tasks. The default implementations is empty.

Reimplemented in gridripper::amr1d::initcond::ODERelaxInit, and gridripper::amr1d::initcond::ODEShootInit.

int gridripper::amr1d::FuncInitCond::getInterpolatedLevel ( ) const [inline]

Gets the minimum refinement level where interpolation is used instead of the precise calculation of the initial state.

Returns:: the minimum interpolated refinement level or zero if interpolation is not used

GReal_t gridripper::amr1d::FuncInitCond::getMostRefinedGridDeltaX ( ) const [inline, protected]

Gets the grid spacing of the most refined subgrids.

Returns:: the minimum possible grid spacing

int gridripper::amr1d::FuncInitCond::getMostRefinedGridMaxI ( ) const [inline, protected]

Gets the most refined equivalent of the base grid size.

Returns:: the size

virtual GReal_t gridripper::amr1d::FuncInitCond::getTime ( ) const [inline, virtual]

Gets the time parameter at the initialization.

The default implementation returns 0.

Returns:: the time

Implements gridripper::amr1d::InitCond.

Reimplemented in gridripper::amr1d::initcond::UserDef.

virtual void gridripper::amr1d::FuncInitCond::init	(	PDE *	pde,
		GReal_t	x,
		FieldWrapper &	phi
	)			throw (InitCond::Exception&) `[protected, pure virtual]`

Initializes the grid at the specified point.

Parameters:

	pde	the PDE
	x	the x coordinate
	phi	output array for the field values

Implemented in gridripper::amr1d::initcond::ODERelaxInit, gridripper::amr1d::initcond::ODEShootInit, gridripper::amr1d::initcond::UserDef, and gridripper::amr1d::initcond::Zero.

int gridripper::amr1d::FuncInitCond::init	(	tvalarray< tvector< Grid * > > &	grids,
		PDE *	pde,
		GReal_t	dt,
		int	r,
		int	maxlevel,
		int	bufzone,
		AMError *	amerr,
		double	maxerr
	)			throw (InitCond::Exception&) `[virtual]`

Creates and initializes base grid and initial subgrids.

Parameters:

	grids	array of all grids
	pde	the PDE
	dt	the time step
	r	refinement ratio
	maxlevel	maximum refinement level
	bufzone	buffer zone size
	amerr	error function
	maxerr	error tolerance

Returns:: the finest refinement level

Implements gridripper::amr1d::InitCond.

virtual bool gridripper::amr1d::FuncInitCond::isNumericalConstraintSettingNeeded ( ) const [inline, protected, virtual]

Tests whether the constraint condition is set numerically by the PDE.

Returns:: true in the default implementation

void gridripper::amr1d::FuncInitCond::setInterpolatedLevel ( int l )

Initial values are interpolated on the specified refinement level and finer levels.

Parameters:

l

the minimum refinement level where interpolation is used or zero to avoid interpolation

void gridripper::amr1d::FuncInitCond::setNumericalConstraintSettingNeeded ( bool v ) [inline, protected]

Enables or disables numerical constraint setting by the PDE.

Parameters:

v

true to set constraints numerically, false if they are initialized by this InitCond
