Hi Daniel
Thank you for your help!
The code below suggests that you want to constraint all degrees of freedom.

I understand my mistake now: there are extra hanging nodes constraints in
the constraint matrix with (hanging nod constraints + PBC) compared to the
constraint matrix with only hanging node constraints.
That is why the minimal example fails.

Dear all,
in the reply to my first post I forgot the code.
I attach it to this reply.

Dear all,
since I am still experiencing the same issue, I tried to solve a very
simple and basic problem
on a domain created with the GridGenerator::hyper_cube_slit and then
rotated of -90 degrees.
As you can see in the attached figures I am experiencing the same issue:
when I run

I agree, the location of nodal points is
Thanks for giving me an idea for this!
I will take a look approaches you just mentioned.

Hello,
I had a few more questions and was some grateful for some clarification:

me an error because for some reason I get
