Summary of results
======================

With a Poisson's ratio :math:`\nu` very close to :math:`0.5`, we find the results of the incompressible analytical solution with a small difference. Note that it is not necessary to explicitly impose the incompressibility condition :math:`\mathrm{tr}\varepsilon =0` in order to obtain good results since the results are almost identical whether one activates or not, the condition :math:`\mathrm{GONF}=0` with DDL_IMPO.
