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

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

The modeling is carried out with 2 POU_D_E elements per type of section. There are therefore 2 groups of elements each comprising 2 elements.

+----------+---------------------+------------------------------------------------+
|Group     |:math:`\mathrm{GR1}`:|rectangular section                             |
+----------+---------------------+------------------------------------------------+
|          |:math:`\mathrm{GC1}`:|circular section                                |

|Elasticity                      |on :math:`\mathrm{GR1}` and :math:`\mathrm{GC1}`|

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


* Beam mesh

:math:`2\times 2` elements POU_D_EM


Tested sizes and results
------------------------------


* Simple traction with :math:`{\mathrm{DX}}^{e}=0.75E-03`
