Hi everyone, I am developing a programm code to simulate the evaporation of liquid nitrogen overflowing/impinging a hot surface.

My first step is just to simulate a multiphase flow without the evaporation process. The flow inlet is on the left side. Attached you can find a file with the set boundary conditions. I think it should not be a problem to simulate that case, because nothing spectacular happens.


However, the problem is that I get some "artefacts" flowing from the outlet to my calculation domain. I think the problem can be solved by fixing the boundary conditions. Does anyone of you know what I should change or what is the problem?


Big thanks!
