Hello Dumux, I am working with the (implicit, box) mpnc-model with a 2p5c fluidsystem and I would like to specify the following inlet boundary conditions to my system: gas pressure, saturation and phase composition. This can be done with a Dirichlet condition and it works fine. But additionally, I would like to set the gas flux into the model domain (basically the pressure gradient) which would mean setting a Neumann boundary condition. Is there a way to do this in Dumux? Secondly, I stumbled across the outflow boundary condition recently what is the physical idea behind this type of boundary condition?
Thanks for your help!
