u2.08.01 Strategies for adapting meshes with HOMARD

Summary:

The purpose of this document is to describe all Code_Aster tools related to mesh adaptation. It is a methodological guide on the best practices to be put in place to conduct a quality study in terms of networking.

Examples of use illustrate the possibilities and the implementation of remeshing strategies.
