about particle tracing in channel

After simulating the velocity in a curved channels, I did not find the right way to predict the movement of particles because I did not find equation or some related options in version 4.0.
The only thing I got is the 'Particle Tracing with Mass' with automatically generated equation.
How can I input inertial lift force, gravity, centrifugal or Dean forces there?
Thank you very much.

I actually encountered the same problem.

Hi,
yes, me also. I've got the same problem. But probably it can be solved via the COMSOL script or/together with MATLAB. Right now, I'm figuring out this way. The script should be able to suppress the built in functions in the GUI, after all the GUI is just a GUI. But very little materials can be found. It's pitty.
Cheers

The 'Particle Tracing with Mass' automatically takes all the forces into account because it computes based on the velocity field that already has these foces "encoded" in it - since velocity field is formed by these forces themselves.
I did manage to visualize e.g. Dean force in a U-shaped channel both by plotting the velocity field on a slice and by tracking a particle through the channel.
The only problem that I could do this only in COMSOL 3.5 but the new 4.0 version seems to be unable to do that.

Hi Daniel,
I've seen your reply about Dean force. Now I'm facing the problem that I cannot visualize Dean force.
It has been a long time since you replied that post, but I need your help very much.
Could you share your way in which you visualize Dean force?
Thank you very much.
Regards,
Joel
