Dear all,
I am storing a std::vector of size N holding global DOF
indices living at some nodes of my mesh where we have measured experimental
values.

Wang,
Do you have a geo file that describes the geometry? Can you remove the
"Physical Surface" lines in the geo file and regenerate the mesh.

Hello,
Thank you very much for your reply. That's what I thought at first, but I
was wrong, when I removed the corresponding physical group it was still the
same error. I think gmsh automatically sets the coupling interface to solid
when drawing the model body mesh, but I don't know how to chang
Hello,
Deal.II associates the physical group of a face with a boundary id. You
need to remove the physical group that are associated with interior faces.

Dear all,
I am trying to use a multigrid preconditioner to solve a PDE with two
domains, in which the resulting matrix will be a block matrix. I am trying
to replicate what is in step-16 tutorial program, but turns out it doesn't
work since there are separate dof handlers for two domains, and I
