Hi Everyone,

I am new to Ansys Fluent and UDF's but have ample experience in CFX. I need to simulate the motion of a moving leading/trailing edge deflection on an airfoil. I will have a non-rigid body so I know I need to use the Grid_Motion macro. I was wondering if anyone can help me set up the UDF. I need to specify the x location for the motion at 25%c and 85%c for leading and trailing edge respectively. I need to set a max deflection of 6 degrees. I need the amount of deflection per timestep to be specified by a equation of motion which I don't have yet but I will.

If anyone is able to help me with this I would greatly appreciate it.
