Dear all,
I am a brand new OpenFoam user. I have some difficulties to understand how fill the boundary information. For example, in the case of icoFoam of tutorials, what is real meaning of nFaces and startFace? How can get information from a mesh? I would very appreciate if somebody can give me an answer.

Regards!

Jack


PS: part of boundary information from the icoFoam tutorials.
