Everything works perfectly in this simpleFoam case of a 2D channel, with the directMappedPatch utility used to achieve the fully developed flow.

But absurdly, when I change ONLY the data in red:

blocks
(
hex (0 1 2 3 4 5 6 7) (20 20 1) simpleGrading (1 1 1)
);

I obtain this error:

Badly formed bounding box0.5 0.25625 0.05) (0.621875 0.378125 0.05)#0 Foam::error:rintStack(Foam::Ostream&) in "/home/om3ro/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so"
#1 Foam::error::abort() in "/home/om3ro/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so"...etc...

I append the compressed files.
Please use the following commands:

blockMesh -> changeDictionary -> simpleFoam

Since you use (20 20 1) in blockMeshDict no error occurs, but try to use (40 40 1) or other combinations and you get the error.

Thanks

In 1.6 it does not like having the directMapped on a coordinate plane. This has been fixed in 1.6.x. Alternatively very slightly perturb your geometry so the patch you are mapping from is not on a plane.

Thanks for reporting,

it works now, thanks!
