i have to simulate an external flow over a 2d NACA airfoil.so,when going through the ICEM Hexa mesh tutarial 2d car.and while spliting the initialize block (in creating the edge ,crossing the bottom of the car at PNTS.12),an error message appears.i try this operation more and more,but i have the same problem. please, i will be very thankfull for any idea or suggestion. cfd user.

Take a look on this Tutorial!

Thanks Rogerio for this tutorial.But my question is: while practicing ICEMCFD 11-Mesh-Hexa-2d car section.And when splitting horizontally the initialize blocking at PNTS.12 on the bottom of the car.An error message appears concerning space or coordinates.i don't know exactly,but i think their is an error some ware.I need any idea from any one who has already done this section yet,or can guide me to an other section example,or brochure concerning meshing and simulating 2d external flow.
