Function Documentation

make_coloring()

void make_coloring	(	const int	m,
		const int	n,
		const int	l,
		int *	icolor,
		int *	lcolor
	)

Coloring algorithm for unstructured grid.

Note

In this function, original multi-coloring algorithm is simplified into Red-Black coloring (checkerboard) scheme due to the properties of hexahedral mesh.

Parameters

m	number of elements in x-direction
n	number of elements in y-direction
l	number of elements in z-direction
icolor	Color Index of each cell
lcolor	Color level of each cell

make_reordering()

void make_reordering	(	const int	nele,
		const int	nface,

	)

Reverse Cuthill-McKee algorithm using neighbor elements.

Parameters

nface	Number of faces depends on element type
nei_ele	Indices for neighbor cells [nface, neles]
mapping	Reordered index by Reverse Cuthill-McKee algorithm [neles]
unmapping	Original index before Reverse Cuthill-McKee algorithm [neles]
