Re: Microparticle in fluid flow modeling
It depends on what you are trying to do. When I did something similar (low RE mixing in a MEMS device), I used the Chemistry module to define the particle distribution as a simple scalar. This made it easier for me to do all the rheology stuff I was interested in (variations in viscosity, density, diffusivity etc). I could of used the User Scalar module, only this wasn't compatible with the free surface flow module I needed for my work (you don't mention an air/water interface so you may not have this problem). FYI, the user scalar module allows for anisotropic diffusion whereas the chemistry module doesn't. If you want to go for full-on particle tracking, then you need the Spray module.
