**d4.06.06** Data structures fiel_no_s and cham_elem_s
============================================================

**Summary:**

This document describes the cham_no_s and cham_elem_s data structures.

A list of the main utilities working on these data structures is also given.

Two new SDs are defined: cham_no_and cham_elem_s which contain the same information as the cham_no and cham_elem SDs but which are "simpler" to handle in Fortran.

There are utilities to transform a cham_no into a cham_no_s (and vice versa) (the same for cham_elem).

These SDs will therefore generally be temporary SDs making it possible to work more simply.

**Important note:**

*The SD* cham_no_s *and* cham_elem_s *are not as general as the SD* cham_no_s *and* cham_elem\ *. For the* cham_no_s *, we only describe the fields carried by the nodes of the mesh (and not the possible late nodes), For the* cham_elem_s *, we only describe the fields carried by the finite elements whose support mesh is a mesh of the mesh (and not a late mesh)*
