The flow in question is laminar with a very small Reynolds number. The domain is curved. The lift and drag coefficients are known.
How can lagrangian particle tracking be used in comsol to determine the particle trajectory?
Hi,
I recommend you to watch the following video in the link.

Hi Mohammed Raihan Uddin if you have your coefficient in a different point, you should introduced your file as a interpolation function to comsol, then the drag and lift can be defined as force in particle tracing module
if you trying to track particles in inertial microfluidic systems there are some paper which can be helpful on of which is attached below:
take look at the supplementary information. the process of mapping lift coefficient is described.

and again if you working on inertial microfluidic and if you need more information
feel free to connect with me.
kind regards
Morteza
Morteza Safari I want to know how the lift and drag forces are used in the particle tracing module once they are given as interpolation function input from a file in the global definitions. More precisely, how is this done in COMSOL?
