I see. So this is a NOX requirement, not something that we could have done anything about on the deal.II side? > The solver does not converge, and the output looks as if it is using > Dirichlet-conditions with u = 0, independently of the "real" boundary > conditions. I don't know NOX, but is it using an update that it adds to the solution in each step? If so, you need to have the correct boundary conditions in the initial guess already. What happens if you only allow NOX to do zero or one iterations?
