**u3.13.13** 2D Modeling_ FLUI_ABSO
=======================================

**Summary:**

This document describes for 2D_ FLUI_ABSO modeling:


* the degrees of freedom carried by the finite elements that support modeling,


* the related support meshes,


* the loads supported,


* non-linear possibilities,


* test cases implementing modeling.

2D_ FLUI_ABSO modeling (Phenomenon: mechanical) corresponds to finite elements whose support cells are linear. They make it possible to take into account the absorbent border condition of sections of fluid volumes, in plane motion.
