abstract void gridripper::amr1d::Dissipation::addDissipation	(	Grid	g,
		PDE	pde,
		int	i,
		double[]	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
