Reply To: Finding Lift force in CG motion UDF

[nahian.masud]

 

yea I reduced the time step. Usually the the velocity range should be below 0.32 m/s and I made the timestep in a way that, the velocity stays in range. But still the lift force is going super high within a few timesteps. I cannot find the reason for it.
and yes, I am moving the airfoil too far away with the force, as it looks like.


alternatively, I was thinking that, I can write the force data in .OUT or .txt file using report definition. Is there any way, to read the force data from that .OUT file and use it in the CG_motion?

thanks
