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

Implemented in gridripper::amr1d::O2Dissipation, gridripper::amr1d::O4Dissipation, and gridripper::amr1d::O6Dissipation.
