Flow Anomaly Near Boundaries

Question asked by Joel Turco on Apr 10, 2011

G'day,

 

We are running a number of external flow scenarios and continue having issues with the flow results near the boundaries of the computational domain.

Our system is fairly simple, we are trying to analyse subsea flow over a simplified seabed and around block shaped objects.

 

We can't understand why the velocity is speeding up near the domain edges (see attached picture).

Our input velocity is in the X-Direction and no matter what velocity we have the same problem.

 

Any help on this matter would be much appreciated.

Thank you!
