**v6.03.119** FORMA20 - Mechanical adaptive mesh on a flexure beam
====

**Summary:**

In this test case, it is a question of ensuring **the non-regression of TP 1 associated with the courses "Error indicators and mesh adaptation; State of the art and implementation in** **Code_Aster"** of the "Nonlinear static analysis with *Code_Aster"** course of the "Nonlinear static analysis with *Code_Aster*" course.

In fact, we distort a **elastic calculation on a bending metal beam** in plane stress modeling. It is **converged uniformly** via the refinement-deraffing tool HOMARD encapsulated in MACR_ADAP_MAIL, then **freely** by coupling the process to a spatial error map located on each finite element.

From the point of view of **computer validation**, this test case makes it possible of course to test the non-regression of various coupling error map calculations/refinement-deraffing procedure in mechanics, but also the "pre and post-processing" options for these calculations (smoothing the constraints at the nodes, transition from an error at the nodes to an error at the nodes by element).

Each modeling is associated with a TP question and we **transcribed most of the correction elements**. The full text of the TP is available on the website http://www.code-aster.com/utilisation/formations.
