		double	dbuf[6]
	)

Parameters

mesh	pointer toward the mesh structure
sol	pointer toward the sol structure.

Build the metric at point ip depending with its type (ridge/not ridge).

	)

Parameters

mesh	pointer toward an Mmg mesh

Returns

1 if success, 0 otherwise

Check the tetra orientation, print warning it negative refs have been detected, mark points as used and remove elt refs in iso mode.

Parameters

mesh	pointer toward the mesh structure.
type	type of the metric
