Hello,

in some cases we use "boundary" file in constant folder to specify the boundary types.
there are two numbers written in front of the "nFaces" and "startFace" ;
what do they mean?
how we can know about these numbers for a new case, that is imported to the openfom through a .msh file (by gambit)?

regards

They indicated the starting face and number of faces, that a certain boundary patch has. Their numbers relate to the faces list. If I were you, I would not just copy-paste the boundary file from one case to the other, just because the gambit import messes the boundary types up. That will f*** up your mesh. Just use sed to replace text in the boundary file automatically.
