**u2.04.01** Tips for using STAT_NON_LINE
====

**Summary**

The objective of this note is to give some advice to a user who wants to perform nonlinear calculations with*Code_Aster* using the STAT_NON_LINE [U4.51.03] operator.

General advice is given first. Then we specify the solutions to be implemented for the main types of problems encountered. The problems in question are of the non-convergence type, or failure of an algorithm. Reference is also made to the documentation specific to each problem.
