flapping wing simulation in fluent
 
2 Attachment(s)
Hello all:
I am current doing fluent simulation on a 3d flapping wing. I have downloaded a udf and tried to view the motion using mesh preview in fluent. However, after I hook the udf to fluent, the wing does not move at all and the fluent just keep giving "wrong" to me. Below is the udf. Anybody can help me with this?:)

Hi, I had the same trouble when I was trying to simulate a 2D oscillating foil. I solved it by reducing the variables in the udf and using more numbers. Hope it helps. Best wishes

if you want to preview Zone Motion, must have to Initialization it before press the Preview.
