Small error at channelFoam case mesh
 
Dear all,

I just found out a tiny error inside the blockmeshDict:
blocks
(
hex (0 1 3 2 6 7 9 8) (40 25 30) simpleGrading (1 10.7028 1)
hex (2 3 5 4 8 9 11 10) (40 25 30) simpleGrading (1 0.0984 1)
);
For the mesh to be symmetric the simpleGrading should be:
(1 0.0934 1)
... or change the first one to (1 10.1626 1). I haven't checked what values make the cells in the center of the channel perfectly square, but with such a small difference I guess is more important to have the same growth ratio.

I've checked versions 1.5 to 2.0.1. It would be nice if the value is corrected for further releases.

Thanks,
Juanma

Greetings Juanma,

Nice catch! I haven't checked this myself either, but if you really want this fixed, then you should report on the official bug tracker: http://www.openfoam.com/mantisbt/my_view_page.php

Best regards,
Bruno

Quick answer: This was fixed in OpenFOAM 2.1.x: http://www.openfoam.org/mantisbt/view.php?id=413

edit: And this fix was included in 2.1.1.
