Dear researchers,
I am working on developing a reliable and accurate COMSOL model to investigate the inertial focusing of particles inside micro-channels. Although I add and define the lift forces (wall-induced and Saffman) and drag forces correctly, my results are incorrect. I believe that COMSOL's wall-induced and Saffman lift forces are not working properly. What can be done?
I would appreciate your insights on this matter.
Hi Mohammad,
I've been investigating the same thing. You cannot define both forces at the same time, because they are not exclusive. Read more into how COMSOL employs both models and how the forces affect the particles. Goodluck :)
Dear Mohammadamir -Amir- G. Moghadam ,
I faced such problem in COMSOL 4 years ago. I was simulating an impact problem. At the end when I read the COMSOL user manual it is written that for impact problems COMSOL does not work well for such cases unless some conditions need to be checked. Therefore, I would recommend you to read COMSOL documents to see if any conditions need to be checked for your case.
Good Luck
