hello every body is there anybody to help me about this problem; for example i want to solve an airfoil drag and lift forces i can do that when the air foil is stationary but how about moving or rotationary air foils,for example,i have an airfoil which rotates in 0.1 rad/sec and i want to see the lift force variation on surface monitor,when i give a rotation speed 0.1 rad/sec to the airfoil there is no different between that case and the same project in stationary air foil when i compare surface monitors any is there anybody help me for this problem

thanks alot
