The example http://sfepy.org/doc-devel/examples/navier_stokes/navier_stokes.html clearly illustrated a NS problem with inlet velocity normal to y axis.
Is it possible to set the inlet with arbitrary plane that is not normal to any axis? e.g. inlet normal velocity = (u1, u2, u3)
I see that in this example the inlet and outlet boundaries are defined by the cinc functions:
how would this utility work with my arbitrary inlet/outlet boundaries?
