Yes, obviously I wouldn't be able to write
assemble(u*dx)
for the trial function u, but I just wanted to show you what I have.
Is it too difficult to design such a non-conventional solver?
Thanks,
Anna.

Hi Anna,Not as written, no. I think that we would need to design a bespoke solver for that.all the best--cjc

Hi all,
I have to solve a problem with the bilinear form similar to the following:
a = ( v*u + dt*inner(grad(u),grad(v)) )*dx + ( v*dt*assemble(u*dx) )*dx
The last term is essentially the product of the integral of u and the integral of test function v.
Is it even possible to solve this in Firedrake?
Best,
Anna.

Any ideas about solving equation (1b), which contains a time-update for both a function and a scalar?I haven't been fully following along, but it looks like the formulation in (1f) introduces, effectively, a global coupling. Is that right? Assuming you didn't have any implementation constraints, how would you go about solving this? Lawrence
