Thank you Wolfgang,
I just realized the new version of step 12. I was working with the older
one, which made it complicated, especially on the inner faces.
Regards,

Hello,
I am trying to install Deal.ii on my new cluster, from the build screen
output it looks there is a problem in finding METIS (which is installed). I
am not exactly sure what is going on? Is there a way to hard code the METIS
Path during the make process? I have attached the screen out fr
OK, I see. I will do it, thank you! I will let you know if I get any result.

Dear Dr.Bangerth,
I did nothing to verify those properties. because the single thread CG
solver converged well. I used different preconditioners in parallel
version and single thread version. In the parallel version I used block
Jacobi and in the single thread version I used Jacobi. How can I
I tried both, first I tried 1e-4*system_rhs.l2_norm(), it failed.
Then either the matrix is not symmetric/positive definite/whatever other
property your iterative solver requires, or your preconditioner is unsuitable.
What have you don to verify that your matrix has the necessary proper

Dear Comunity,
I would like to open again the topic with another question. Is there any
way to use the Meshworker to solve the DG formulation but using block
matrix and vectors? I couldn't find a proper way to do it with the
