Reply To: Finding Lift force in CG motion UDF

[nahian.masud]

There is no single constant value. The force is changing every timestep due to changing angle of attack (as it has oscillating pitching motion). So how can I use the updated force value, that is generated from the fluent solver?

Also can you please tell me, how to modify the vel[1] so that my lift force does not go super high?

thanks
