u3.14.10 3D Modeling_ FLUI_ABSO

Summary:

This document describes for 3D modelling_ FLUI_ABSO:

• 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.

3D modeling_ FLUI_ABSO (Phenomenon: mechanical) corresponds to finite elements whose support meshes are surface. They make it possible to take into account the condition of the absorbent boundary of fluid volumes.
