Hey, i've your same problem! how did you resolved it? Please i'm getting mad! I'm trying to simulate a cylinder at Re=1e+7 with a Cd expected of 0.8 but i'm not getting this value at all. Could you help me to understand how to resolve it? Thanks!!

Hi Danny,

can you please send me the sim file. It should fit into an email when you clear the mesh and solution. I have some ideas, but don't want to do the setup from scratch.
