[Pw_forum] Convergence during vc-relax

[Sergey Lisenkov]

Dear PWscf authors,

I am performing variable-cell relaxation of unit cell of my structure. Firstly. I performed atomic relaxation. My calculations were finished without any informations:

     atom  12 type  1   force =     0.00000952    0.00008130   -0.00004912
     atom  13 type  2   force =     0.00004235    0.00005128   -0.00004270
     atom  14 type  2   force =     0.00005058   -0.00004839   -0.00005341
     atom  15 type  2   force =     0.00004395   -0.00000478    0.00006488
     atom  16 type  1   force =    -0.00000257    0.00001235   -0.00008447

     Total force =     0.000348     Total SCF correction =     0.001318

Where is output geometry, output cell parameters? As I remember, in past versions it was printed during each step, in this version (2.1) no information at all. Does it mean convergence or not? What is criteria of convergence in vc-relax?

 Thank you very mcuh,
   Best wishes,
