ns_parallel_block_sweep()

void ns_parallel_block_sweep	(	int	n0,
		int	ne,
		int	neles,
		int	nfvars,
		int	nface,
		int *	nei_ele,
		int *	icolor,
		int *	lcolor,
		double *	fnorm_vol,
		double *	rhsb,
		double *	dub,
		double *	diag,
		double *	fjmat
	)

Lower/Upper sweep of Block LU-SGS with multi-coloring algorithm.
This function is used for Euler or Navier-Stokes equations, which has the same flux shape.
solution array is stored in dub array.

Note

The last argument array, fjmat is NOT identical with ns_serial_pre_blusgs function.
For more details, refer to the Block LU-SGS in the document.

ns_parallel_pre_blusgs()

void ns_parallel_pre_blusgs	(	int	neles,
		int	nfvars,
		int	nface,
		double	factor,
		double *	fnorm_vol,
		double *	dt,
		double *	diag,
		double *	fjmat
	)

This function computes diagonal matrices of the implicit operator using multi-thread computing.
In Block LU-SGS method, implicit operator is approximated with block operator. Diagonal matrices is composed of block operator matrix, which size is n-by-n. n is the number of conservative variables in Navier-Stokes equations.

parallel_update()

void parallel_update	(	int	neles,
		int	nvars,
		double *	uptsb,
		double *	dub,
		double *	subres
	)

solution array is updated by adding \(\Delta Q\).
