Function Documentation

void GetCurrent	(	Data_Arr	V,
		double **	curlB,
		Grid *	grid
	)

Parameters

[in]	V	A 3D array of cell-centered primitive quantities
[out]	curlB	A 1D array containing two components of the current in a the direction set by g_dir
[in]	grid	a pointer to an array of Grid structures

void ResistiveFlux	(	Data_Arr	V,
		double **	RF,
		double **	dcoeff,
		int	beg,
		int	end,
		Grid *	grid
	)

Compute resistive fluxes for the induction and energy equations. Also, compute the diffusion coefficient. Called by either ParabolicFlux or ParabolicRHS.

Parameters

[in]	V	3D data array of primitive variables
[out]	RF	the resistive fluxes
[out]	dcoeff	the diffusion coefficients evaluated at cell interfaces
[in]	beg	initial index of computation
[in]	end	final index of computation
[in]	grid	pointer to an array of Grid structures.
