I'm writing a program for electro-osmotic flow. I will need to solve the momentum eq. to obtain the pressure at the walls. Must I write a new code for doing that? (I guess I'll need to use fixedGradient???) If I do, where can I find a good example? Thanx!

Seems that no body cares to response. Does anybody know where I can find a good example to start with? Thanx!

fixed gradient with explicit u
fixed gradient with explicit updates interpolated from the interior is the best I can think of as a short term solution. Might need some under-relaxation to keep things steady.
