Hi:

SORRY for my repeated email, really sorry.

I have read the documentation about "3D Mesh Generation" (Chapter 50)
and I cant find how I can solve my problem. I want to do the same as
example  "50.3.3 Domains From Segmented 3D Images", but I want to
define my set of points. I have to create a triangulation with
subdomains, where I need to consider only my set of points. Is there
any form to impose my set of points and have subdomain? because in my
problem I need to know in which subdomain is each tetrahedron and
impose my set of points.

Best Regards
Jc
