We examine the influence of roofs' shapes on the boundary layer of a simplified urban canopy by computing non-stationary Navier-Stokes flow over a periodic pattern. The solution is obtained by means of finite element method (FEM). The resulting linear system is solved by the multigrid method. We present computational studies of the problem.
