Unsteady Flow-Time Step Size -- CFD Online Discussion Forums

March 5, 2009, 10:50	Unsteady Flow-Time Step Size	#1
Maple Guest Posts: n/a	Hello, I using unsteady flow option in fluent to solve a non-premixed combustion problem. I need to define the number of steps and the steps size. The total chamber length is around 250mm and the maximum velocity is around 0.5 cm/s. Please anyone could tell me what should be the number of steps and the step size, and also the max. number of iteration. How should i calculate them? Thank you very much.
