Hi everyone,

I have a slight problem. I am using Fluent14 to attempt to model high Re Cylinder Flow in 2D and see if it gives remotely accurate results. There is however something very odd happening with the Lift Coefficient.

The lift coefficient oscillates as it should do with a reasonable period however it does not oscillate around 0 despite the mesh being symmetrical and the flow in being uniform. The mesh is structured and uses 2 Ogrids around each other to mesh the cylinder itself. Around this is H grid. The Cylinder is relatively very small compared the flow domain so edge conditions should not have any effect on the Lift Coefficient.

Any help with this would be much a appreciated.

Thanks,

Matt
