Hi everyone, I have just joined your nice Forum

I am simulating the magnetic capture of micromagnetic particels carried by liquid flowing through a microchannel. The Fluent theory manual lacks some important issues related to the grid-to-particle  sizes. The micro scale flow and the high gradient of the external magnetic force require me to resolve the grid (2D) into a comparable and even smaller than the 2D area of a particel (dp=1e-6m).
I will highly appreciate clarifying the constraint (if any) on the minimum cell size for both Eulerian-lagrangian model and for DPM model (and DDPM if possible)
