Dear Sir Thank you very much for the quick response. I have changed the cell information to below but still have the same problem. I think my below positions are symmetric. If not then please suggest how I can generate the symmetric position. I have also run the job with "use_all_frac=.true.," i

[QE-users] What is the difference between 'relax' and 'vc-relax' when cell_dofree is set to '2Dxy' ?

Dear QE users, I am trying to understand the difference between 'relax' and 'vc-relax' when cell_dofree is set to '2Dxy' in the case of 2D structure relaxation. According to the help files, the 'relax' mode only moves the ions and the 'vc-relax' mode move both the ions and the cell parame

[QE-users] Binding energy for Graphene-metal interface

2020-11-29 Thread wallexact--- via users
Hello All, I started using QE this month and I'm interested in calculating the binding energy of graphene/cu(111) interface using just 1x1 unit cell of both. I used vesta to create the cu(111) slab and also join the graphene with the cu(111) slab. I have an input file but I'm not certain if I got
