Hello, dear OF users. I am investigating a pipe of diameter X, which has a common inlet divided for gas and liquid. This pipe also has an outlet of diameter X. In addition, there is a tube of 6 times smaller diameter (Y), flowing out of this pipe. I am wondering what boundary conditions need to be set to make the liquid in the smaller diameter tube the same as in the larger tube. Is this possible at all? I have tried opening all the outlets and setting the pressure either in the cell to zero or at the main outlet. I am using the interFoam solver with the k-omega turbulence model.

Thanks in advance!
