setEdgeBuilderVersion()

virtual void Arcane::IMeshUniqueIdMng::setEdgeBuilderVersion ( Integer n )

pure virtual

Sets the edge numbering version.

Valid values are 0, 1, and 2. Value 1 works regardless of the number of cells, but the mesh must be read by a single processor. Value 2 only works if the maximum of the node uniqueIds() does not exceed 2^31.

If the version is 0, there is no renumbering. In parallel, the uniqueIds() of the faces must be consistent between subdomains.

setFaceBuilderVersion()

virtual void Arcane::IMeshUniqueIdMng::setFaceBuilderVersion ( Integer n )

pure virtual

Sets the face numbering version.

Valid values are 0, 1, 2, and 3. The default value is 1. If the version is 0, there is no renumbering. In parallel, the uniqueIds() of the faces must be consistent between subdomains.

setUseNodeUniqueIdToGenerateEdgeAndFaceUniqueId()

virtual void Arcane::IMeshUniqueIdMng::setUseNodeUniqueIdToGenerateEdgeAndFaceUniqueId ( bool v )

pure virtual

Indicates whether the uniqueIds() of edges and faces are determined based on the uniqueIds() of the nodes they consist of.

This method must be called before setting the mesh dimension (IPrimaryMesh::setDimension()).

If active, when an edge or face is created on the fly, MeshUtils::generateHashUniqueId() is used to generate the uniqueId() of the entity. This allows automatically creating edges or faces in parallel.

Warning

If this mechanism is used, it should not be mixed with the manual creation of edges or faces (via IMeshModifier) or you must use MeshUtils::generateHashUniqueId() to generate the same identifier as the one created on the fly.
