MMG5_cavity_ani()

int MMG5_cavity_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	iel,
		int	ip,
		int64_t *	list,
		int	lon,
		double	volmin
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the sol structure.
iel	tetra index.
ip	point local index in iel.
list	pointer to the list of tetra in the shell of edge where ip will be inserted.
lon	number of tetra in the list.

Returns

ilist number of tetra inside the cavity or -ilist if one of the tet of the cavity is required.

Mark elements in cavity and update the list of tetra in the cavity.
