Is it possible to count the number of particle hits (using a Lagrangian Discrete Random Walk scheme) on the walls, using the Fluent interface (without using UDFs)? If not will UDFs help? Can someone point to some references to work related to such tracking?

Thanks

Hi, If by particle hits you mean particles being trapped, yes you can. in the injections panel, enable discrete random walk and set number of tries, then track particle in the display paticle tracks window. I hope this helps.

Thanks for the reply. I have tried this and this works well.
