    I am a dealii amateur from China. Recently, I encouter a problem when 
programing with the dealii lib (version 9.2.0). When I output the sparsity 
pattern using method BlockSparsityPattern:: print_gnuplot(), it can 
successfully output a data file. But we found that some indices are out of the 
range allowed either for the row or column. I don't known why. I guess that 
this may be caused by the constraint arising from the periodic boundary 
condition applied. But I have no ideal how to fix it. Could you provide me 
some tips on how to solve this problem? Thank you very much.


K. Wang:
It's hard to tell what is going wrong because we don't know from your message 
at what point during the program's execution you are outputting the sparsity 
pattern, or which specific entries you are trying to write to but that you 
can't. Can you create a small program that illustrates the issue you are facing?

Re: [deal.II] Re: error while installing dealii using candi

2022-07-21 Thread Ahmad Shahba 
By using the -j1 argument, you are requesting candi to use 1 process for
compilation. If you are interested to engage, say 2 processes, you should
pass -j2 to the candi shell script. Something like

./candi.sh -j2

If you visit the github homepage of candi, you’ll see a whole bunch of
options for controlling the way candi goes about compiling and installing
deal.ii and its dependencies.

Thank you for your suggestion. JOBS = 1 is the default in candi.sh and
passing -j1 does not make any difference. Could it be related to the flag
-std=c++17? How can I impose it?

Thanks for your help
Erkin
