Detailed Description

First order (donor cell, piecewise constant) spatial reconstruction.

PURPOSE: First order (donor cell, piecewise constant) spatial reconstruction.

• The L/R-states at the left-interface in each cell are indexed i.
• W_{L,i-1/2} is denoted by Wl[i ]; W_{R,i-1/2} is denoted by Wr[i ]
• W_{L,i+1/2} is denoted by Wl[i+1]; W_{R,i+1/2} is denoted by Wr[i+1]

CONTAINS PUBLIC FUNCTIONS:

• lr_states() - computes L/R states
• lr_states_init() - NoOp function in this case
• lr_states_destruct() - NoOp function in this case

Function Documentation

void lr_states	(	const GridS *	pG,
		const Prim1DS	W[],
		const Real	Bxc[],
		const Real	dt,
		const Real	dx,
		const int	il,
		const int	iu,
		Prim1DS	Wl[],
		Prim1DS	Wr[],
		const enum DIRECTION	dir
	)

Computes L/R states.

Input Arguments:

• W = PRIMITIVE variables at cell centers along 1-D slice
• Bxc = B in direction of slice at cell centers
• dtodx = dt/dx
• il,iu = lower and upper indices of zone centers in slice W must be initialized over [il-1:iu+1]

Output Arguments:

• Wl,Wr = L/R-states of PRIMITIVE variables at interfaces over [il:iu+1]
