DPM droplets size limitations for a given cell size (or vice versa)
 

Hello,

I'm simulating diesel droplets combustion (non pre-mixed), in which uniform 1micron diameter droplets are being injected throught a single injector into a relatively very large domain (2D 1x2 meters)

The question is what should be the meshing cell size?
What are the constraints? How big can a cell size be than a droplet size?

Thanks!
