major Guest Posts: n/a	hi,ereryone: my model is about water/gas mix steady flowing in a big vessel and with a free surface in the top vessel. I use eulerian multiphase model. But I don't know how to define the boundary condition of free surface because I can not use eulerian and vof models at the same time. Please illustrate your good ideas. Thanks for any suggestion!
