Sorry, I wanted to say, that the imposition of boundary
conditions in the setup is apparently dominant.
Is this the general case in your applications?
Thank You

Is this evaluation sound, should I strive for better times?

Hello,
problem was,
- that I have some meaningless calls for
/*current_solution_phase.reinit(locally_owned_dofs_phase,
locally_relevant_dofs_phase, mpi_communicator);
current_solution_phase = 0;
*/
/*solution_update.reinit(locally_owned_dofs_phase,
Hi Marek,
If you do manage to determine an acceptable solution, perhaps you'd be
willing to post the solution for other to reference at some later stage?
Thanks,

Hello,
I believe I solved partially the problem, do
not bother to answer the thread without my further

Hello,
I am developing code in the Step-40 like setting - Cahn-
Hilliard Navier Stokes system. I am witnessing very poor
performance of startup for large problems.
For the system with
1458 dof for Cahn Hilliard
47000 dofs for Navier Stoke
I got the following results (4 computer cores)
Setup CH,
