4.2. notes#

Relative differences are greater than 2% for \(t=400.s\), lower for \(t\ge 600.s\)

On the surface, the results calculated by*Code_Aster* are symmetric with respect to the \(\mathrm{AC}\) diagonal. The maximum difference observed, in relative as well as in absolute terms, is 0.29%, or \(1.4°C\), between point \(A\) (\(\mathrm{N291}\)) and point \(D\) (\(\mathrm{N179}\)) at the moment \(t=400.s\). These differences decrease in absolute value as time increases.
