Reference problem
=====================


Geometry
---------

The geometry of the problem is that of a cube with side 200 and whose faces are called :math:`\mathit{Face1}`, :math:`\mathit{Face2}`, :math:`\mathit{Face3}`, :math:`\mathit{Face4}`, :math:`\mathit{Face5}` and :math:`\mathit{Face6}`.


Material properties
----------------------

It is an isotropic linear elastic material with Young's modulus :math:`1.` and Poisson's ratio :math:`0.3`.


Boundary conditions and loads
-------------------------------------

The cube is embedded on its side :math:`\mathit{Face1}` while all the others are subject to fluid pressure.


Initial conditions
--------------------

The initial conditions are free of any displacement and constraints.
