4.1. Characteristics of modeling#
The mesh is done using TRIA6 of the D_ PLAN_HM_P modeling.
The coordinates of the points are given in the following table:

We also test the computer non-regression of the global components ESTERG1 and ESTERG2 of the error indicator. Absolute tolerance is therefore severe: \({10}^{-13}\).
