In Espresso, you can use shapes as boundaries for the fluid. Moreover, you can prescribe the velocity on the surface of the boundaries. See the section12.9. Using shapes as lattice Boltzmann boundary
in online ESPResSo documentation
For Couette flow, you can set an upper and a lower rhomboid with the opposite velocities to create shear flow.
