d5.02.02 Introduce a new mesh type or reference element

Summary:

This document describes what to do to introduce a new mesh type in*Cod* e_Aster or a new reference element.

In a few words, to add a new type of mesh and/or a new reference element, you must:

• define and introduce the characteristics of the mesh and/or the reference element in the Code_Aster source: node position, connectivity, shape functions, position of Gauss points,…

• think about the impact on existing functionalities in Code_Aster,

• enrich the « user » documentation (Doc U) and the « reference » documentation (Doc R) relating to the mesh file, shape functions,…

• enrich existing test cases in order to test your new finite element.

A complete example will be described in this document.
