Hi everyone,

I am trying to model two phase flow through a microscale triangular channel in 3D. I'd like specify the liquid flowing in one direction and the vapor (phases are immiscible) flowing the other direction. I have one inlet and one outlet. See attached for a (poorly drawn) sketch of the domain. I've looked in this forum and on Google Scholar to find instances where people have done this successfully using VOF. I found a few papers that claim to have done it, but they do not give any details on the actual simulation setup.

In particular, I am interested in how to set up my BCs in order to achieve this. Any tips?
