◆ addLinkedCells()

void Arcane::ExternalPartitionConstraint::addLinkedCells	(	Int64Array &	linked_cells,
		Int32Array &	linked_owners )

virtual

Adds a set of constraints on the cells.

Adds to the linked_cells array a set of pairs of uniqueId() of cells that must remain in the same partition. For example, if cells 25 and 23 must remain connected, it is enough to call:

linked_cells.add(23);

linked_cells.add(25);

You must always add pairs of uniqueId(), potentially repeating the cells. For example, if one wishes that cells 35, 37, and 39, one must do as follows:

linked_cells.add(35);
linked_cells.add(37);
linked_cells.add(35);
linked_cells.add(39);

The linked_cells array must have a size that is a multiple of 2. The linked owners array indicates for each pair which subdomain it must belong to.
