Thanks Wolfgang, very silly of me. Have sorted the other problem too which
didn't have anything to do with the way i was interpolating boundaries.

where the boundary values are just 1.0 so that u is a constant vector field.
this still gives me the bizarre 22 factor in my pressures solution
(which is just linear in z - the resulting pressure solution is atleast
linear), but the pressure solution aside
Hi Wolfgang, thanks for a swift reply.
and apologies, I wasn't very clear.
when I'm imposing dirichlet conditions everywhere, i don't have a condition
for pressure (those were two separate test cases - sorry i was unclear).
and i'm using:
VectorTools::interpolate_boundary_values (
I'm trying to solve a stokes system with some funny boundary conditions
so I've stripped the code to make sure I was getting the correct answers
to a very simple system as follows:
governing equations are:
div grad u + grad p = f
div u = 0
i'm setting u=0 on the boundaries, giving u=0 (or close
Hi all,
This may seem like a very obvious question/mistake on my part so please do
excuse me if I've overseen something very simple.
