mehdiataei New Member Mehdi Join Date: Jan 2017 Posts: 17 Rep Power: 9	Hi all, Im trying to simulate growth of a bubble (1D) due to diffusion of gas from the liquid into the bubble. I am using interFoam solver. I have a couple of questions: 1) I want to set a boundary condition at interface of the two phases e.g. The concentration at the interface is a function of bubble interior pressure. How can I set such a boundary condition while its position is constantly changing with the growth of the bubble. 2) Is it also possible to introduce mass generation at the centre of the bubble (a point instead of a face)? Thanks!
