I am trying to run a 3d case of flow past cylinder in Fluent. I have set the drag and lift monitors on the surface of cylinder wall (i.e. where the no slip condition is given). I am running the case for Re of around 120. I am getting proper vortex shedding at this Re validating the experimental results, however at this Re the drag coefficient should be around 1, whereas in my simulations the monitors show the drag coefficient to be zero. What could be the reason for this incorrect drag and how can I sort it out??

Hi,
At SOLUTIONS - Monitors
At Convergence Monitors: Forces/Surfaces. See picture.
Good luck
