**u3.01.00** Code_Aster mesh file description
==============================================================

**Summary:**

This file allows you to describe a *Code*\ _\ *Aster* mesh. It can be built by an automatic interface between a mesher and the code, but can also be written by hand. It contains:


* a possible title,


* a list of nodes with their coordinates,


* lists of meshes, each mesh is described by the list of nodes that defines its topology, and its orientation,


* node groups and mesh groups.

**Note:**

*A concept of the type* *mesh, once read on the mesh file, can be enriched using Code_Aster operators with information that cannot currently be described in the mesh file. This concerns in particular static substructuring. In addition, it is now possible to create groups of knots or meshes during the study.*
