This is my first thread in the forum. I am trying to solve a 2d axisymmetric swirl steady state problem using a multiphase flow VOF model, laminar flow. After marking the region where VOF is of a 1 value and identifying this in the boundary conditions at the flow inlet. After the solution is converged, I found in the graphic results that:

Contours>>Phases>>volume fraction>>Phase-2
Min: 1 , Max: 1

this makes all the interior value as a same color. And this is pretty not indicative.
Could you please assist to identify the problem?

Thanks!
