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. Yves. sébastien janas <[email protected]> a écrit : > hi, > > I am using the python interface of getfem.
