B modeling
==============


Characteristics of modeling
-----------------------------------

A longitudinal section of the cylinder is modelled in 2D volume elements, considering the axisymmetry hypothesis.

Characteristics of the mesh
----------------------------

The cylinder is represented by a regular mesh of quadratic elements with 8 nodes containing:


* 4 elements;


* 21 knots.

The mesh contains 2 cuts in the radial direction and 2 cuts in the vertical direction.

    ":math:`{U}_{X}` in :math:`\mathrm{P2}` ", "1", "0.44203108"



note
--------

Modeling more efficient than 3D because 2 cuts in the radial direction and no circumferential discretization.
