UDF for pitching motion of a 2D airfoil -- CFD Online Discussion Forums

mahdihasan New Member Mahdi Hasan Join Date: Oct 2017 Posts: 9 Rep Power: 9	Hi, I am asking help to do a simulation of an oscillating airfoil that has sinusoidal pitching motion like alpha= 10(degree)+10sin(10t). I will simulate it using Ansys Fluent but have never used UDF before. The airfoil movement will be constrained by the function. I believe that the UDF function will be very simple and I really don't have an idea of what and where to add the function. I'd really appreciate if you can help me. Thanks.
