Welcom everyone,
I am working on the problem of high pressure hydrogen outflow into open space. I am trying to use 2nd order unsteady problem and 2nd order discretization solution (pressure, density, momentum, species fractions and energy). I have a problem with boundary conditions pressure-outlet. The computation is converged to the moment when the pressure waves reach an edge of the domain with 'pressure outlet' bc. Did anyone work with 2nd order and 'pressure-outlet' bc? Thank you very much for help.
