2nd order discretization -- CFD Online Discussion Forums

September 28, 2009, 09:15	2nd order discretization	#1
Pavel O New Member Join Date: Sep 2009 Posts: 4 Rep Power: 16	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.
