Detailed Description

Base class for a mesh element.

Mesh elements are nodes (Node), cells (Cell), faces (Face), edges (Edge), particles (Particle) or degrees of freedom (DoF). Each of its elements is described in the corresponding derived class.

This class and its derived classes are lightweight objects that are used by value rather than by reference and should not be kept between two modifications of the family (IItemFamily) they are associated with.

Regardless of its type, a mesh element has a unique identifier (localId()) for its type and local to the managed subdomain and a unique identifier (uniqueId()) for its type across the entire domain. The numbering is continuous and starts at 0. The local identifier is used, for example, to access variables or for connectivity.

For example, if a mesh has 2 hexahedral cells that join by a face, there are 12 nodes, 11 faces, and 2 cells. In this case, the first node will have identifier 0, the second 1, and so on up to 11. The first face will have identifier 0, the second 1, and so on up to 10.

There is an entity corresponding to a null object. It is the only one for which null() is true. No operation other than calling null() and comparison operations is valid on the null entity.
