udf in fluent
Hello to everyone..

This is my first post in CFD online.. I am trying to simulate pitching airfoil problem in fluent using the udf posted in this forum. The problem i am facing is that the airfoil starts oscillating either above or below the chord line at zero angle of attack ie, it is no showing sine function variation in its motion.. I am new to udf programming.. couldn't sort out the exact problem of it.. please provide me some guidance in regard to this.. Thanks..
