Dear Sebastien,If you have to prescribe a zero Neumann condition to your unknown (assuming that it is an order two isotropic pde), you do not have to add anything to your model. This is somehow a default boundary condition as it add nothing to the weak formulation.

hi, I am using the python interface of getfem. I want to impose the normal derivative of my unknow to zero at the boundary, but it seems that the model method "add.normal_derivative_source_term" don't exist, is it correct ? If yes, what's the best way to impose such a condition on a model ? Thanks a lot for your help, Sébastien _______________________________________________ Getfemusers mailing list address@hidden https://mail.gna.org/listinfo/getfemusers
