Using importGeometry and pdegplot (PDE toolbox),
N = 3;
model = createpde(N);
importGeometry(model,'BracketWithHole.stl');
pdegplot(model,'FaceLabels','on')
the geometry is decomposed into different faces as shown in the picture. How to access to the vertices and the facets (triangles of the mesh) of each labeled face ?

Hello,
I was able to associate nodes to faces thanks to this answer:

Thank you for your time.

First you have to create the mesh:
generatemesh(model);
If you have the latest MATLAB version (R2016b), you can view the mesh nodes and element labels using pdeplot3D. Sorry, I know of no way of obtaining the labels programmatically.

Hello,
I am facing the same problems. I would like to assign boundary nodes to faces in order to describe the solution over the faces. It seems impossible that there is no way to distinguish the boundary nodes from the face label. The geometry is imported as STL file. Thank you for your attention
Best Regards
Gaetano
