Good morning everyone,

I am trying to simulate a droplet of oil with radius of 2mm fall into a waster base with radius of 10cm and I use setField to initialize the droplet and water base, however, the after 0.4 seconds, the Delta T became some number around 1.5e-16 and the max courant number is around 0.13. ( I use the adjusted timestep), which make no sense to me.

Beside that, by viewing under paraview, I found that the droplet is not even a sphere(actually, I can't even see it). So I doubt the capacity of OpenFoam dealing with such a small droplet.

Can anyone give me some hint about why is this can and how to make it works?

Many thanks!
James
