Detailed Description

Numerical dissipation term on the grid.

Member Function Documentation

virtual void gridripper::amr1d::Dissipation::addDissipation	(	const Grid &	g,
		const PDE *	pde,
		int	i,
		tvalarray< GReal_t > &	dfdt,
		int	exclude
	)			`[pure virtual]`

Adds a dissipation term to the time derivative.

Parameters:

	g	the grid
	pde	the PDE
	i	the grid point index
	dfdt	add the dissipation term to this time derivative
	exclude	binary flags corresponding to constant field components for which the dissipation term must NOT be added

GReal_t gridripper::amr1d::Dissipation::evalSigma	(	const Grid &	g,
		int	i
	)			const `[protected]`

Evaluates sigma.

Parameters:

	g	the grid
	i	grid point index

const Sigma& gridripper::amr1d::Dissipation::getSigma ( ) const [inline]

Gets the dissipation term multiplier.

void gridripper::amr1d::Dissipation::setSigma ( const Sigma & s ) [inline]

Sets the dissipation term multiplier.

Parameters:

s

the dissipation term multiplier

virtual string gridripper::amr1d::Dissipation::toString ( ) const [pure virtual]

Gets a string representation.
