The problem with Fluent's Discrete phase model is that the particles pass through the barriers regardless of their diameter, for example if the gap is 500 micron and the particle diameter is 1 mm, the particle passes through the gap. Can anyone guide me.

Can any one help me in this regard. Did you got the answer to this problem Mr.Khashayar.If you have solved your problem can tell me how you have implement this work. Thankyou.
