NRBC and pressure based solver

ageorg · August 27, 2009, 13:26

Dear all,

I would like to know why the Non-Reflecting Boundary condition option is not available with the pressure based solver.
I am modeling a unsteady multiphase granular flow and i am using pressure outlet boundary condition for the open flow boundaries of the computational domain. I am using the pressure based solver as the density based one is not available in conjunction with the eulerian multiphase model. Hoe can i check that the downstream boundary conditions do not introduce any spurious waves.

Thanks very much in advance,

Ageorg
