Hi All,
I tried sHM my external flow model.
What I got is this error

Surface refinement iteration 0
------------------------------

Marked for refinement due to surface intersection : 0 cells.
Marked for refinement due to curvature/regions : 14 cells.
Determined cells to refine in = 0.22 s
Selected for refinement : 14 cells (out of 165486)

What should I do nest to get my sHM working? Help!

Greetings Lana,

You're not providing much information to work with... from the error message, I can only assume that it's having trouble with meshing around a highly detailed part of the geometry, which leads to problems. Or the geometry is has some flaws that are hard to work with.

And you're using OpenFOAM 1.6.x ? Is there any chance you can upgrade to OpenFOAM 2.2? Because snappyHexMesh is a lot better in OpenFOAM 2.2...

Best regards,
Bruno

PS: I suggest that you read this thread: How to give enough info to get help
