I opened the struct file with Xcrysden and I found that the primitive cell has a=b=c. Now, I am convinced for 10x10x10 k-points. Thank you very much for your reply. ** Nacir GUECHI Dr. Physique de la matière solide.Enseignant-Chercheur à

Hi, kgen generates the k-points for the primitive cell, which has a=b=c in your case (open your struct file with xcrysden and press F3 to see the primitive cell). F. Tran thank you for reply. my query is: why the same number 10 in the plane and out-plane?

The general approach is to increase the k-mesh until the results converge "adequately". I deliberately added quotes, as everything depends upon what you are trying to do! I don't know for certain, but I would wonder about whether +U or -eece is needed for the Fe -- in which case your are obtaining

For a tetragonal system: RbFe2As2 ( a=b=7.407923 Bohr,  c= 29.324817Bohr), it has a space group 139_I4/mmm. Notice that it has a primitive cell. The Kgen (wien2k 18.1, wien2k 17.1, wien2k 14.2) for 1000 k-points produces: NUMBER OF K-POINTS IN WHOLE CELL: (0 allows to specify 3 divisions of

Dear wien uses, I've made a new release, which contain all the bug fixes discussed so far for version 18.1. It is a minor update and upgrade from 18.1 is only necessary if you are using gfortran (lapw1 + iterative diag) pes nlvdw 3ddens For details see

Dear Dr. Victor, I am looking for the bandstructure of a compound in which the mixed valence state exists for an element between +2 and +3 states. Now I want to find the bandstructure for both +2 and +3 states, that is why I asked the question in the forum. thanks, On Tue,
