[Pw_forum] convergence of relaxation caculation

[Hande Ustunel]

Dear Meisam,

You would still need to provide input and output because "doesn't converge"
means very little out of context. We need to see what that means. Besides,
5 scf cycles is not very many cycles. Is it possible that you mean atomic
steps? Even so, it's still acceptable.

I didn¢t change any parameters and they are in default mode. I used automatic meshing BZ,1*1*8.also I have not fixed any position. in output , after 5 scf cycles the system doesn¢t converge. I think if I  disrupt the position it would converge but I don¢t know how I could make this system converge.  
 
Thanks for your attention.
