jam Member Alain Martin Join Date: Mar 2009 Posts: 40 Rep Power: 17	Hi all, What is the function to access the total number of faces ( triangles) on each boundary? I have this function: Info << "number " << mesh.boundaryMesh()[0] << endl; which give: patch patch0 5506 945258 for patch no 0. I would like to extract the number 5506 from this lot to do some calculation. Thanks, -Alain
