I am trying to run a vof simulation of a droplet impinging on a roughened flat plate from an inlet flow. Since running the simulation for the whole domain will take a long time, I am planning to use only one by fourth of the domain. I am concerned whether I can proceed this way or not?
if yes, what boundary conditions do I need to set up which divides my domain.

Hi Nitisha,

You can run VOF simulation with periodic boundary conditions. But, you have to make sure that when you divide the geometry, the resultant quadrants are all same.
