How to access the number of faces on a boundary

jam · January 20, 2008, 13:01

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

I found it:

scalar number = mesh.boundaryMesh()[PatchID].size() ;

where PatchID is the patch number.
