Dear Lawrence,
Thank you very much for the detailed reply. So if I understand correctly, I have to define the forms for A_form, Q1_form, Q2_form, rhs_form and use the bits of code you sent me.
I hope so, note that I just typed it into the email so there are probably many other issues other than the one below.
If I do that, I get the error "Exception: Linear forms must be defined using test functions only: (1, 'k', 4, 4)" for Q2_form = mu*dx
where mu is a trial function. So is it not possible to assemble a vector using the trial function only?
I think you can just use a test function from the appropriate space instead (the result will turn out the same I believe).
