Hello,
In the following COMSOL file, I am trying to change the behavior/movement of particles near the wall by using various numbers and variables for reflected particle velocity (vp) (In both cartesian and tangential-normal coordinates), general reflection, wall condition in particle tracing physics but the problem is nothing changes and the particles have the same movement all over again. For instance, I see the same results in animation section, while choosing 10000 (t) and 0 (n) or 0 (t) and 0 (n) or … , for reflected particle velocity (vp) in both coordinates.
I really need help with this matter.
Thank you in advance.
