Strange velocity contours

MJBarrera · April 19, 2017, 05:39

Good morning to everyone in the forum,

I'm trying to run a 3D steady state simulation with k-epsilon realizable model and non equilibrium wall functions, and after aparent convergence, I get this strange velocity contours around the hull I'm studying, anyone has any idea why ?

Thank you.

Hi,
are you using parallel processing for your case? if so, do your simulation again with single processor.
i think it is a graphical bug duo to do parallel processing.

If this is the cause of the problem then you have to repartition the case into a single partition. Otherwise you will run in serial mode, but still on the partitioned grid.
