◆ _broadcastGroups()

void Arcane::MEDMeshReader::_broadcastGroups	(	ConstArrayView< String >	group_names,
		IItemFamily *	family )

private

Broadcast the groups of group_names for the family family.

The list of groups group_names is only used for rank 0.

◆ _readAvailableTypes()

void Arcane::MEDMeshReader::_readAvailableTypes	(	med_idt	fid,

Retrieves the list of geometric types present in the mesh.

◆ _readFaces()

void Arcane::MEDMeshReader::_readFaces	(	IPrimaryMesh *	mesh,
		Int32	mesh_dimension,
		med_idt	fid,

private

Reads the faces.

There is no need to explicitly create the faces because this is done automatically in Arcane. We therefore use the MED faces only to add the faces into the corresponding groups in the mesh file.

		const MEDToArcaneItemInfo &	iinfo,
		Array< Int16 > &	polygon_nb_nodes,
		Array< med_int > &	connectivity,
		Array< med_int > &	family_values )

private

Reads information about entities of a given type.

Reads information about entities whose type is given by iinfo. The entities are cells in the MED sense, i.e., Edge, Face, or Cell. Returns the number of entities read. connectivity will contain the connectivities for the entities read and family_values the array for each entity of the family it belongs to. Note that family_values may be empty if there is no family associated with the entities.

If the type is MED_POLYGON, then polygon_nb_nodes will contain the number of nodes for each polygon.
