Dear prof. Bangerth,
Thank you so much for your help.
Yes, I tested the make_grid part on a separate sheet. As long as my size is
41*41*37, the time cost did not go down, i.e. approx. 90-110 s.
However, your solution 'coarse mesh + global refinement' did help, now it
only cost 20s :)
Thanks

Dear Simon and prof. Bangerth
Thanks for your kind replies. The issue finally turned out to be that I set
a 'smoothness' when I defined the triangulation ( my supervisor found it,
he is a deal ii deep lover XD).
I have a further question though. The background is that, I am doing some

Hi,
Did you call
triangulation.execute_coarsening_and_refinement();
after setting the refinement flag?
Best,
