Hi all, How can I compute the timestep in transient flow?? thanx

Hi Zaher,

Do a timestep independance study. Choose a sensible sounding starting point, do a simulation, get an answer. Rerun with half the timestep. If the answer is the same you should be timestep independant. If different then rerun with the timestep halved again. Keep repeating and halving the timestep until you get the same answer.
