Dear FOAMers,

I build a case using the geometry in this link

After performing blockMesh -> surfaceFeatureExtract -> snappyHexMesh, it seems the mesh is Okay

Using the checkMesh along or checkMesh -allTopology to check it, everything is fine. (See the attached checkMesh-allTopology.txt)

However, using checkMesh -allGeometry, failed 3 mesh checks. (See the attached checkMesh-allGeometry.txt )

Though I've asked in another thread, and @tomf told me care about only checkMesh results. I've follow that suggestion, until recently.

Some of my cases, it starts fluently, and after a long while, the solution becomes slower and slower.
When I extract the temperature along the centerline, there's empty value on some cells near the exit.
I wonder if it's the mesh quality issue?!

If I should be concerned about the quality of the mesh created, what issue should I deal with first and how to deal with it?

Thank you FOAMers!

Best regards,
Mactone
