October 18, 2017, 07:13	UDF for pitching motion	#1
ronak Member Hanye Azimi Join Date: Oct 2016 Posts: 42 Rep Power: 10	Hi there I'm using a UDF in order to simulate a pitching motion for a Naca0012 airfoil. Whole the domain rotates. on the UDF the velocity is defined : dv= pitchAmplitudesin (omegadt) and it is right so the lift number is calculated correctly. The thing is that there is no definition for mesh motion sth like this: y= Amplitude * sin ( omega*t) As I'm not familiar to the C++ I don't know how to put it in the UDF. Would anyone help? thanks
