Function Documentation

void all_species_pullback_weight	(	const Grid< DeviceType > &	grid,
		const MagneticField< DeviceType > &	magnetic_field,
		const DomainDecomposition< DeviceType > &	pol_decomp,
		ElectricField< DeviceType > &	electric_field,
		Plasma &	plasma,
		int	direction
	)

Perform the pullback transformation on all non-adiabatic species.

Parameters

[in]	grid	is used to get weights for the field gather
[in]	magnetic_field	is needed for psi and B calculation
[in]	electric_field	is used for magnetic potential Ah
[in]	plasma	contains all species and particle data
[in]	direction	is the direction of the pullback (-1 or 1)

Returns

void
