Dear freind now i am working on particle tracking, and i would like to familiar with a cfd code in particle tracking, can you tell me about particle tarcking method in fluent. particle tarcking in fluent is very fast and this is very strange.i will be appeciated for your help. Thanks ------------lhWusNLd2tvjK9dB4dD+8n

Fluent 6.3 - tut 16

Low accuracy -> fast code

Dear Joe Thanks for your guide in cfd-onlin.com about particle tracking code, I read Fluent6.3 tot, but I want to familiar with process of particle tracking, at first fluent track one particle after this fluent should search in whole grid and find particle new coordinate in domain, of course this is my guess, is this correct? With this method particle tracking must be time consuming, but particle tracking in fluent is very fast. Finally, particle tracking in fluent6.2 and Fluent6.3 has an error especially in Brownian motion and another aspect. Fluent6.Is reliable. Best Regards, Morteza
