hi there,

i'm implementing an Inflow-Outflow type of boundary condition(instead of a periodic condition), and using the ghost cell approach for the longitudinal direction. I'm seeking informations or references dealing with setting the velocities for the ghost cells. Sincerely,

Frederic Felten.

Hi, Frederic, About mathematical and numerical boundary conditions for primitive and conservative variables you can read in the book by Charles Hirsh, Numerical Computation of External and Internal Flows ( vol. 2, Ch.3). I have used those recipes (for the ghost cell in incoming and outcoming boundaries), it worked very well. Good luck,

Svetlana
