It's a piece of my own code. Here's an extract:
class BoundaryFlux(Expression):
def eval(self, values, x):
if abs(x[0]) < DOLFIN_EPS and x[1] > 0.2:
values[0] = 1.0
else:
values[0] = 0.0
g = BoundaryFlux( V = V_cg)
bc = DirichletBC(V_cg, g, DirichletBoundary())
A = assemble(a)
b = assemble(L)
bc.apply(A, b)
The error is at 'bc.apply(A, b)'.
