The cylinder is in the infinite field, material air, Diameter of cylinder 1m, Re=10000. Model RNG,k-epsilon. I'm changing only tubulent kinetic energy and tubulent Dissipation Rate. And the resut is Cd=0.58, in case it should be approximatelly 1.1-1.2. Maybe someone had done similar work, and have some advices. Regards, Mindaugas
