https://answers.launchpad.net/dolfin/+question/93169

    Status: Open => Solved

dbeacham confirmed that the question is solved:
After reading through the tutorial on fenics.org I managed to sort this
out using the following for any others who have a problem (effectively
augmenting the cahn-hilliard demo with an extra argument):

class MyProblem(NonlinearProblem):
    def __init__(self, a, L, ext_facet_domains=None):
        NonlinearProblem.__init(self)__
        self.a = a
        self.L = L
        self.ext_facet_domains = ext_facet_domains

    def F(self, b, x):

    def J(self, A, x):
