.. _D9.05.01: **d9.05.01** Implementing STAT_NON_LINE and DYNA_NON_LINE =============================================================== **Summary:** Here we describe the computer implementation of the algorithm for solving nonlinear, nonlinear, and dynamic, nonlinear problems. The documents describing these algorithms in detail are supposed to be known ([:external:ref:`R5.03.01 `] and [:external:ref:`R5.05.05 `]), we will only recall the main steps. In this document, we will find a summary of the notations, the simplified flowchart of the op0070 routine, making it possible to discern the main logical joints of the operators STAT_NON_LINE and DYNA_NON_LINE of *Code_Aster*, the call tree, a description of computer objects and the main routines, and a few pitfalls to avoid during development in this operator.
