Function Documentation

MMG5_kPartBoxCompute()

int MMG5_kPartBoxCompute	(	SCOTCH_Graph *	graf,
		MMG5_int	vertNbr,
		MMG5_int	boxVertNbr,
		SCOTCH_Num *	permVrtTab,
		MMG5_pMesh	mesh
	)

Parameters

graf	pointer toward the input graph structure.
vertNbr	the number of vertices.
boxVertNbr	the number of vertices of each box.
permVrtTab	the new numbering.
mesh	pointer toward the mesh structure.

Returns

0 if ok, 1 otherwise.

Internal function that computes a new numbering of graph vertices using a k-partitioning and assuming that baseval of the graph is 1.

MMG5_scotchCall()

int MMG5_scotchCall	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pSol	fields,
		MMG5_int *	permNodGlob
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the solution structure.
fields	pointer toward an array of solution fields (non mandatory)
permNodGlob	store the global permutation of nodes (if provided).

Returns

0 if MMG5_renumbering fail (non conformal mesh), 1 otherwise (renumerotation success of renumerotation fail but the mesh is still conformal).

Call scotch renumbering.

MMG5_swapNod()

void MMG5_swapNod	(	MMG5_pMesh	mesh,
		MMG5_pPoint	points,
		double *	sols,
		MMG5_pSol	field,
		MMG5_int *	perm,
		MMG5_int	ind1,
		MMG5_int	ind2,
		int	solsiz
	)

Parameters

mesh	pointer toward the mesh
points	pointer toward a table containing the point structures.
sols	pointer toward a table containing the solution structures.
fields	pointer toward an array of solution fields to permute.
*perm	pointer toward the permutation table (to perform in place permutations).
ind1	index of the first tetra to swap.
ind2	index of the second tetra to swap.
solsize	size of the solution.

Swap two nodes in the table of vertices.
