The beam is meshed using HEXA20 elements.

Boundary conditions:

At point :math:`A` such as :math:`X=0.1`, :math:`Y=0`, :math:`Z=0`:

:math:`\mathrm{DX}=\mathrm{DY}=\mathrm{DY}=\mathrm{DRX}=\mathrm{DRZ}=0`

On the other hand, all the nodes in the section passing through :math:`A` are rigidly linked.
