Hi, Yes you can choose P instead of F. Beside this, it is important to reduce the symmetry (e.g., from cubic to orthorhombic) for atoms with an open shell (most free atoms are magnetic) in order to reach the proper electronic ground state. I attached the struct file (P) that I used for a free Na

​Dear users. I am trying to calculate cohesive energy. As it is mentioned in FAQ, we must create FCC supercell and also use identical RKmax and RMT. Now i have two question? 1- Can i choose Cubic (P) supercell instead of FCC. In other words, is there any reason for that choosing? 2- what is

Orthorhombic means that the lattice constants a, b and c are not equal. P means primitive, which is one of the lattice types (see Table 4.4 in users's guide). The unit cell for Na has orthorhombic symmetry and is of lattice type P. The wave function of the electronic state with the lowest total

​Thank you dear Tran. It was completely helpful.But what is the role of symmetry in calculating cohesive energy as you said reduce cubic to orthorhombic for open shell atoms.Also for Na which is open sell, you use P instead of orthorhombic. ___ Wien

Since I'm interested in the parity(+/-) on the high symmetric points, shifting k-vectors arbitrarily from those points will not gonna help in my case. I checked the structure by grep PGBSYM *, and turns out that it is a nonsymmorphic structure. Can you give me another idea/trick to

Dear Wien2k community and Prof. Blaha, I am trying to do spin orbit calculation of a system having both d and f electrons. When I am doing spin orbit calculation with magnetization along z direction it is fine but when I am changing the magnetization direction (e.g. 100, 110 etc) then select
