Hello,

with the default setup the simulation diverges, this is not unintended. The angle of attack is to high and the airfoil stalls. Try to play around with the simulation parameters, mainly the angle and the airfoil profile and you should see that with a lower angle and/or a different airfoil the simulation does not diverge.
