atmosphere bc in dam brake case (interFoam solver)
for the simulation of a falling liquid film I would like to use an atmosphere boundary condition similar to the one used in the dam break example presented in the User's Guide. For the pressure field the totalPressure and for the velocity field the pressureInletOutletVelocity boundary condition is used.
Is there any documentation explaining how these boundary conditions work in detail? Especially the determination of U and pd at inlet is not clear to me.
