Melanie Jahny is still having a problem:
Thank you for your quick answer!!!
I think I'm using the newest fenics version 0.9.4.
I tried the new code, and it works:
du = TrialFunction(V)
dF = derivative(F, u, du)
problem = VariationalProblem(F, dF)
But I cannot get the solution of the problem, I can neither call:
problem.solve(u)
nor
solver = NewtonSolver("lu")
solver.parameters["convergence_criterion"] = "incremental"
solver.parameters["relative_tolerance"] = 1e-6
solver.solve(problem, u.vector())
What can I do to get the solution???
