I am working on a simulation of a microfluidic system that involves both the effect of dean flow and inertial (lift) forces on particles travelling inside a microchannel. To my knowledge, COMSOL is able to compute and display the dean effect on the particles flowing through the microfluidic channel. However, I could not find any display of inertial forces equations which restricted my simulation - separation of flowing particles from one another with respect to their size/volume could not be done. So, I reckoned that I should insert my own ODE's that represent the relative inertial force. However, I am having trouble understanding the parameter representation and the process of equation insertion into my component.
I would really appreciate an assistance on whether there is a representation of such effects (inertial force effects) built-in in COMSOL, or if not, on how I would be able to use my own equations in my analysis.
Thank you.

I asked this problem to Comsol company, then it just said 'you use the force term in particle tracking module'
But now I still don't know how to add the inertial lift force.
If you solve the problem, remaining the comment. Thanks.
