Hi Timo, Thank you for your answer, as it clears up the issue. Apparently I was following a wrong trail. I was supposing that the “outflow” had been removed because it was not working right, instead of not being general enough. Since my oil-water program was crashing as soon as I put in the outflow condition, I was blaming it. Lldb was not of much help, but gdb pinpoints that I have not correctly initialized the saturation field.

It was removed because the implementation wasn't general enough. There is, to our knowledge, no general implementation that works for all physics/equations and has the same semantics in all cases. I see that an outflow is now to be specified by constructiong the element solution, evaluating the gradient and calculating the flux. That's _one_ possibility of implementing an outflow boundary in case of the box scheme. In an example I see that the templates for elementSolution and evalGradients are used. I am quite sure that a similar approach can be used somehow in 2.12 if I knew exactly where to start looking. Am I right? If so, where should I start looking? Your question is unclear to me. Yes, you can do exactly the same as in 3.0 (why not?), except that you have to implement the evalGradients function yourself. But you might end up with exactly the implementation of the "outflow BC". If you are happy with outflow in 2.12, why would you implement it in a different way in 2.12? Maybe you can reformulate your question?
