structured grid data

George

Hi evrybody, does anyone knows where I can find the geometry data of a cylinder of an internal combustion engine. I have written a code for simulating 3D,unsteady, turbulent flow in curvilinear coordinates and I am willing to test it. But the geometry is missing. I have seen some internet-sites that provide these data, but under authorization only. Or if you have them in a .dat file,can you pleasy send them to me? My e-mail is gkosmadakis@gmail.com

Thank you in advance!
