Hello all,

I trying to add refinement regions to my mesh by using snappyHexMesh but for some reason it doesn't let me do that.

You can see my "blockMeshDict" and "snappyHexMeshDict" files attached.

blockMeshDict.txt

snappyHexMeshDict.txt

I checked my "searchableBox" coordinates but nothing seems wrong.

Can you please help me to find the problem?

Thanks,

Greetings kilroy,

This tends to happen a lot with snappyHexMesh I personally end up not using layer addition by sHM and use refinement levels instead of layers.

Nonetheless, I suggest that you check the very useful presentation "A Comprehensive Tour of snappyHexMesh - 7th OpenFOAM Workshop (25 June 2012)" for more ideas: http://openfoamwiki.net/index.php/SnappyHexMesh

Best regards,
Bruno

Thank you very much for your reply Bruno. I found the problem now. It is because of my "blockMeshDict" file. I did a mistake with my vertices.

vertices
(
(-35 -0.04 -17.5)
( 55 -0.04 -17.5)
( 55 0.04 -17.5)
(-35 0.04 -17.5)
(-35 -0.04 17.5)
( 55 -0.04 17.5)
( 55 0.04 17.5)
(-35 0.04 17.5)
(-35 -0.04 17.5)
( 55 -0.04 17.5)
( 55 0.04 17.5)
(-35 0.04 17.5)
);

z-coordinate of the points above shown with red, should be zero.

After fixing that, my "snappyHexMesh" started working properly again

Sincerely,
Kilroy
