4.1. Tested values of modeling A#

We calculate the function \(\mathit{diff}\) defined as being the difference between the absolute displacement of node \(\mathrm{NO2}\) and that of node \(\mathit{no2}\). And we check that it is really zero for various moments.

We also test the value of the absolute displacement of node \(\mathit{NO2}\) for various times.
