Hello everyone,

I am trying to incorporate a multiphase model on my SIMPLE 2D Fortran code, and the first benchmark problem I solved was "Breaking of a Dam" (Dambreak). I defined a no-slip BC on top, but now I want to define an Atmosphere boundary condition.
I am looking for an adequated set of boundary conditions and how to discretize them,in terms of velocity and pressure.

I will greatly appreciate your suggestions.


Regards,


Marcelo M
