Boundary conditions
----------------------

For the cube free of lateral deformations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

These boundary conditions relate to modeling a.

The following movements are imposed on the faces:

• BAS :DZ = 0

• GAUCHE :DY = 0

• ARRIERE :DX = 0


Modeling
------------

All models are 3D.
