**r4.07.05** Homogenization of a network of beams immersed in a fluid
============================================================================

**Summary:**

This note describes a model obtained by a homogenization method to characterize the vibratory behavior of a periodic network of tubes bathed by an incompressible fluid. Next, the development of a finite element associated with this homogenized model is presented.

The tubes are modelled by Euler beams and the fluid by a potential model.

This modeling is available in command AFFE_MODELE by choosing 3D model_ FAISCEAU.
