Given the number of a face, how can I identify if it is on a patch of type "empty"?

[t.oliveira]

Use:

label facePatchId = -1;
facePatchId = mesh.boundaryMesh().whichPatch(faceID);
const polyPatch& pp = mesh.boundaryMesh()[facePatchId];
if (isA<emptyPolyPatch>(pp)){
    // face faceID is on patch of type "empty".
}

Hi Thomas,


I think you can also do it this way when you try to determine whether the type of patch is empty.

label facePatchId = -1;
facePatchId = mesh.boundaryMesh().whichPatch(faceID);
const polyPatch& pp = mesh.boundaryMesh()[facePatchId];
if (pp.type()=="empty"){
// face faceID is on patch of type "empty".
}

The type() function return the type. Hope this will help you.
