3.3. notes#
The boundary conditions, \(T=100°C\) on \(\mathrm{AB}\), and \(T=0°C\) on \(\mathrm{AD}\), 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 \(A\) is \(0°C\).
