Boundary condition on mesh

Sorry, Your question too vague, you can get the list of label of mesh3 Th int[int] labs = labels(Th); cout << labs < endl; or you can build the surface mesh load “msh3” laid “medit” Th = buildBdMesh(Th); // build the surface mesh meshS Th1 = Th.Gamma; plot(Th1,wait=1); medit(“Th1”,Th1); // to see label of region of Th1 …

You can also found boundary labels more conveniently with built-in function “labels” as
int[int] labs = labels(Th);
