**u2.04.02** Tips for implementing non-linear calculations
===============================================================

**Summary**

The objective of this document is to give advice to a user who wants to perform non-linear calculations with*Code_Aster*. The user of linear calculations will also find useful information and advice.

The following aspects will be addressed:


* meshing and modeling,


* loads and boundary conditions,


* materials and laws of behavior,


* non-linear resolution,


* memory/time management and optimization,


* error control and quality.

This document does not treat issues specific to dynamics.
