notes
---------

The boundary conditions, :math:`T=100°C` on :math:`\mathrm{AB}`, and :math:`T=0°C` on :math:`\mathrm{AD}`, are incompatible at point A.*Code_Aster* applies an "overload law" which, in this case, consists in taking into account the last limit condition entered. The order in which the temperatures imposed are assigned therefore has a major influence on the results obtained.

In the case treated, the temperature affected at point :math:`A` is :math:`0°C`.
