Thank you very much Felipe for the very fast and precise answer. For the record: I have checked the "Overall domain bounding box" line after running the checkMesh application and I realized that the coordinates are of the order of thousands (thereby I have concluded that the channel height H is indeed considered as 1186.84 m).
Hence, I will re-scale the coordinates by trying both solutions of the given thread on CFD-online forum. Cheers, Cris On Tue, Jun 11, 2013 at 2:11 PM, F. A.
