Hello, I was wondering if someone could help me with a simple problem - I'm looking to be able to obtain the total number of points in a certain boundary (say, "wall"). I know to obtain the total number of points one needs, say:

int nPoints = mesh.nPoints();

But how do I do this for just one specific boundary?

Hi Verse,


The following is my idea, I hope it can help you.

//First of all, you need to get the patch you are interested in, for example, "movingwall"
const label patchI = mesh.findPatchID("movingwall");
const fvPatch& patch = mesh.boundary()[patchI];
//Then return the total points in the patch
const label ntPoints = patch.nPoints();

Thanks Jerry! Works perfectly, really appreciate it.
