MMG5_scale_meshAndSol()

int MMG5_scale_meshAndSol	(	MMG5_pMesh	mesh,

		double *	dd
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward a metric
sol	pointer toward a solution structure (level-set or displacement).
dd	pointer toward the scaling value (to fill)

Returns

1 if success, 0 if fail.

met	pointer toward the metric structure.
dd	scaling value.

Returns

1 if success, 0 if fail.
