Dear Support Center,
I performed a fluid flow simulation (turbulent, k-epsilon) and then a particle tracing one. I employed 1000 particles and used "bounce" as a wall condition. This is fundamental to me. However, at the end of the simulation, I obtain a warning stating:" Some particles have been removed from the simulation because maximal number of wall interactions within one time step has been reached." Increasing the number of particles to 5000, I also obtain the following:" Some particles have been removed from the simulation because of a failure in finding the wall intersection."
What should I do? Thank you very muhc. Best regards, Andrea Giordano.

Hello Andrea, I'm facing the same kind of problems. Did you find a solution for your problem?? If so, could you please explain me how you did it??
By the way, do you know how to generate a residence time distribution curve?? I've been trying it for days, but I cannot overcome this problem.
Thanks in advance for any answer. Jhoan
