Member Function Documentation

boolean gridripper::amr1d::initcond::BData::isOnInitialHypersurface

(

)

[inline]

Is the the initial condition applied on the initial hypersurface?

Returns:

true if it is applied on the initial hypersurface, false otherwise

Reimplemented from gridripper::amr1d::InitCond.

boolean gridripper::amr1d::initcond::BData::isAppended

(

File

f

)

[inline]

Should the output be appended to an existing data file?

Returns:

true if output should be appended, false if an existing data file can be overwritten

Reimplemented from gridripper::amr1d::InitCond.

int gridripper::amr1d::initcond::BData::init	(	Grid	grids[][],
		PDE	pde,
		double	dt,
		int	r,
		int	maxlevel,
		int	bufzone,
		AMError	amerr,
		double	maxerr
	)			[inline, 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.

double gridripper::amr1d::initcond::BData::getTime

(

)

[inline, virtual]

Gets the time parameter at the initialization.

The default implementation returns 0.

Returns:

the time

Implements gridripper::amr1d::InitCond.
