Thank you JP,
your hints are highly appreciated. I will work on creating my own data
structure, to see how complex and effective it can be. In the meanwhile
though I made some tests with "almost" zero volumes cohesive interfaces and
they are indeed simple and effective. So, if there is a chance
Hi Alberto,
This is simply not possible. The deal.II triangulation contains as much
information as it needs, and we do not associate a normal with a volume.
Normals are computed internally (and not stored!) based not only on the
geometry of each real but also the mapping associated with the

As a short follow up of the former question, I wonder how to pass
geometrical information to a triangulation, if they are not included in the
file read by grid.in(). As an example connected to the problem described
above, consider the notion of "normal" at point 1/2 (in 3D: normal at the
Thank you Wolgang and Jean Paul.
In these days I made some implementation in the line you propose but I am
not happy with it and thus I am asking advices on a different path of
reasoning.

Dear community,
I am asking some advices on the following issue. I am solving a simple
problem, say a Poisson problem in the unknown field u, and a more involved
problem separately. This second problem requires the values of u in the
Neumann boundary conditions.
Accordingly, I guess one could
