Fills the "correspondance" structure and the "sous_domaine" for part "part".

Look for the vertices belonging to the sub-part, compute the renumbering arrays for vertices and elements between global and local numbers (correspondance structure), fill the sub_domaine structures (vertices, elements, boundaries, joints, etc). Note: sous_domaine must be an empty object (not containing a domain)

		const Static_Int_Lists_t *	som_raccord = nullptr )

Generation of all sub-domains of the computation and writing to disk of the files basename_000n.

Domains for 0 <= n < nb_parties_. If "sous-domaines" are defined (in the domain.ss_domaines() field), a file is also generated per sub-domain.

WARNING: this method might change elem_part!!! (if 'reorder' option was specified)

◆ initialiser()

		const int	nb_parts,
		const int	epaisseur_joint,
		const bool	permissif = false )

Prepares the data structures for building sub-domains based on a partitioning provided in elem_part.

Parameters

(domaine_global)	the domain to partition (must have a domain). A reference to this domain is stored (it must remain valid).
(elem_part)	for each element, the number of the sub-domain to which it belongs, with 0 <= elem_part[i] < nb_parts. Note: a reference to this array is stored, not a local copy. The array must continue to exist until DomaineCutter is no longer used.
(nb_parts)	total number of sub-domains
(les_faces)
(epaisseur_joint)

◆ reset()

template<typename _SIZE_>

void DomaineCutter_32_64< _SIZE_ >::reset ( )

cancels all references and empties the arrays
