Dear Antoine, You can use add_generalized_Dirichlet_condition_with_multipliers(mim, varname, mult_description, region, dataname, Hname) instead, see http://getfem.org/python/cmdref_Model.html?highlight=dirichlet_condition#getfem.Model.add_generalized_Dirichlet_condition_with_multipliers

With this kind of code, I have to prescribed the displacement in the 3 directions How can I just precribed the displacement in only one direction, and let the others free ? Thank you in advance for your advices ! -- -- *Antoine Mazuyer <http://www.ring-team.org/component/liad/?view=user&limitstart=0&id=589> * | *PhD.
