I would be heavily surprised if you get correct results without calling
Triangulation::add_periodicity() if you are using discontinuous elements
and a serial
Hi Jie,
thanks a lot. The link to your repository was very helpful. I could
significantly reduce the number of iterations using your implementation
of computing the pressure laplacian through:
K_p = B diag(velocity_mass_matrix)^-1 B^T.
I have tested the dependence of the preconditioner on

it is parallel distributed triangulation?

Great,
Thank you Dr. Bangerth, I will start to look from some of the book. Thank
you for all of your help.

Thanks! Now it becomes clear to me.
By the way, when I 'add_periodicity', I have compiler error on the red line
of the code.
Can you give me a clue to resolve this error?
