EX_NAVIERSTOKES8 2D Example for axisymmetric incompressible stationary flow in a constricted circular pipe.

[ FEA, OUT ] = EX_NAVIERSTOKES8( VARARGIN ) Sets up and solves stationary axisymmetric Poiseuille flow in a constricted circular pipe. The inflow profile is constant and the outflow should assume a parabolic profile. Accepts the following property/value pairs.
