If you are using schemes for compressible flows, you perhaps
need to add a preconditioner to your solver. Almost all
schemes developed for compressible flows have accurracy and
convergence problems for low Mach flows. If you are using an
incompressible solver, you'd better try some other schemes
or finer mesh near boundary. Good luck.
