Default outflow BC for Karman vortex street
Ingo Meisel
Posts: n/a
Hi all,

I'm trying to compute a Karman vortex street with FIDAP 8.60. I want the outflow boundary condition to be du/dt + const * du/dx (damping of reflected waves at the outflow boundary of the computational domain, not disturbing the vortices that are convecting downstream, and fulfillment of continuity equation). How can I implement this rather complex boundary condition in FIDAP? Any comments/suggestions are welcome.

Regards, Ingo Meisel
