Dear Franco,
what type of triangulation are you using? If you look at the code that is run
with `update_cached_numbers`

you will see that the numbers are updated (just as
Xiang,
deal.II interprets physical tags as boundary ids when reading .msh files
using GridIn::read_msh (
https://www.dealii.org/current/doxygen/deal.II/classGridIn.html#a83872db02e04f52ac52d578912f6da5e
).
If your mesh consists of multiple parts in separate msh files you can
create triangulation
Hi, can Dealii read the inside boundary from .gmsh file, which can
distinguish different parts of model geometry? If it can not, how can
dealii import the model with multiple parts? Thanks a lot.
Best,
Xiang

Dear Luca,
thanks for your answer, I've moved along but I am still encountering
problems in the interpolation. This seems to be a problem with the way I
use PETSc.
So, as far as I understand, I need to initialize a PETSc vector of length
n_global_particles * components (in my case, 2, the
