Summary0000413: Small error at channelFoam case mesh
DescriptionDear 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
