I made the C type grid with 50C*50C dimensions with blunt trailing edge. Everything is good untill when I am trying to simulate it at higher AOA like 16its showing me the vorticity near the two face connections at the trailing edge which seems to be quiet unreal. anybody knows how to fix the problem. I am attaching the pictures of the airfoil vortices at AOA 16. http://img32.imageshack.us/img32/3418/62143078.jpg http://img6.imageshack.us/img6/1402/16041239.jpg http://img7.imageshack.us/img7/9769/92423939.jpg http://img6.imageshack.us/img6/3161/15773007.jpg Case file link: http://www.4shared.com/file/13324788...rfoil0012.html
