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


Geometry
---------

It is an assembly:


* of a parallel-piped with a length :math:`10.m`, a width :math:`3.m` and a depth :math:`1.m`,


* of a rectangular plate with a length :math:`10.m`, a width :math:`3.m` and a thickness of :math:`1.m`,


* of a beam with a length :math:`10.m` and a rectangular cross section :math:`3.mX1.m`.
