Function Documentation

void fluxCorrection	(	Vector &	Flux,
		const Vector &	AvgL,
		const Vector &	AvgR,
		int	AxisNo
	)

This function apply the divergence-free correction to the numerical flux.

Parameters

Flux	Numerical flux vector
AvgL	Left average vector
AvgR	Right average vector
AxisNo	Axis of interest

Returns

void

{
    auxvar = Flux.value(AxisNo+6);

    Flux.setValue(AxisNo+6, Flux.value(AxisNo+6) + (AvgL.value(6) +    .5*(AvgR.value(6) - AvgL.value(6))
                                          - ch*.5*(AvgR.value(AxisNo+6) - AvgL.value(AxisNo+6))));

    Flux.setValue(6, ch*ch*(AvgL.value(AxisNo+6) + .5*(AvgR.value(AxisNo+6) - AvgL.value(AxisNo+6))
                                          - .5*(AvgR.value(6) - AvgL.value(6))/ch));
