It reaches a frozen state in which the solution does not change with time anymore! I have provided two planar snapshots of the flow fields for p=5 (first) and p=6 (second) below: [image: p=5.jpg] [image: p=6.jpg] As you can see in the images above, p=6 resulted in a weird wake pattern (frozen in time) which is not physical either. My case is a 3-D low-Re flow and I am using the incompressible solver. I was wondering if something may be wrong with what I am doing, or if there is a specific issue with the numerics. Any help would be appreciated. Kind regards syavash
