Hi,
The separator has one inlet and three outlets, the inlet has a bc with the mass flow of each face (oil, gas and water), and the outlets also have a mass-flow bc but only with the phase that corresponds (oil, gas or water). The VOF is enabled with the implicit formulation and the implicit body force, the primary phase is gas. The operating conditions are 50psig and I've put it on the gas phase (0;1.2;0). The density operation is the density of the gas phase. I've used a Coupled scheme with the PRESTO! solver for pressure and BGM solver for VOF. The problem is that the fluid starts to float, and the residuals start to increase. These are some pictures.
