karthik1414 is on a distinguished road
hello everyone,

I was trying to simulate a horizontal, turbulent, stratified two-phase flow (liquid- gas) using twoPhaseEulerFoam.

First, I tried using funkySetFields to generate the internal fields for the phase velocities and then I tried taking the internal field as uniform.
Both the times it did not work, so I tried changing the velocities of the two phases to zero and just let the two phases flow in the domain, but still it was not working.

I tried changing the scheme from Euler to steadyState, but it showed errors and crashed. (The courant number was oscillating from 300 to 0.08, eventhough limitation of 0.1 was imposed)
In the beginning, I had tried doing it with interfoam (vof method), then it was working.

Please give me some suggestions and advice on simulation of horizontal, turbulent, stratified two-phase flow (liquid- gas) using twoPhaseEulerFoam.

regards,
Karthik
