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


.. csv-table::

    "Number of nodes:", "123"
    "Number of meshes and types:", "20 QUAD9"



notes
---------

Volume heat :math:`\rho {C}_{P}` is not a step in this test, but must be declared. We take :math:`\rho {C}_{P}=2.0J/{m}^{3}°C`

Boundary condition :math:`\varphi =0` is implicit on free edges.
