Hi
I have modeled a two-phase flow(VOF) in microchannel. Red color is water and Blue color is air. I have done my problem's mesh by ICEM. In your opinion, what is the problem with my modeling?
As you see in the picture I have something strange in my flow(I circled around them).
Inlet BC is mass flow inlet and Outlet BC is pressure outlet.
Thank you
