Hi everyone,
I am trying to simulate couette flow. As you may know the analytical solution of NS when the pressure gradient is neglected gives a linear velocity distribution between the two plates. I try do do with COMSOL but I can't figure out how I can make dp/dx=0. I tried point pressure constraint to fix the pressure but I always get non linear velocity profile between the plates.Anyone can help to get linear velocity profile.
