Default Drag coefficient and inlet problems
Posts: n/a
Hey, i am modelling unsteady flow past a circular cylinder and when i run the analysis initially i should get a cd value of zero. However this is not what i am geting even though the results look correct after this initial error. Does anyone have any suggestions? I have modelled the problem with a velocit inlet.
