Summary of results ====================== The results obtained with*Code_Aster* coincide well with those of code POUX (reference solution). For modeling :math:`B`, they are very similar (:math:`\text{<}4.0{10}^{-4}`) except for the case of gravity load, :math:`3\text{\%}` of maximum difference, because of the dependence of the solution on the fineness of discretization.
