Message #01979
form integration
Hi,
I stumbled over the following which seems peculiar to me:
P2 = VectorElement("Lagrange", "triangle", 2)
DG = FiniteElement("Discontinuous Lagrange", "triangle", 0)
ME = MixedElement([P2, DG])
(v, q) = TestFunctions(ME)
(u, p) = TrialFunctions(ME)
a = q*p*dx
Now, FFC insists that the degree of the above form is 4 and it will therefore
use 3x3 integration points. For tensor representation this will lead to an
increase in FFC compile time, for quadrature an increase in runtime.
Is this a bug? Or something that happens for a good reason and which is hard to
do anything about? What will UFL do?
