Impulsive Start Problem [Dynamic Mesh]
 

Hi all,

I am a student and have to complete a project for a course. I have to simulate the flow over a airfoil which is in hover and moving with constant speed along x-direc. But, I am not able to move my airfoil by UDF. I defined the airfoil as wall zone and nothing else. I have uploaded the cas and udf file to the following link. Can anybody say what the problem is? I did go through the oscilating membrane tutorial and played with the UDF in it and there is no problem.

Thank you.
