Backward Facing Step: Incompressible NS

Hello,

I am trying to find a MATLAB code for the 2-D, nondimensional, incompressible, laminar Navier-Stokes equations to simulate low speed air flow over a backward facing step.

[Precise Simulation]

There is an examle for flow over a backwards facing step using the FEATool Multiphysics toolbox
