Dear experts, I am having a compact cluster with 100gb RAM, 36 cores and 12 TB SATA hard disk with CentOS. I want to calculate the band structure by considering the van der waals interaction of 6ql topological insulator. Below are the steps I have used for the detailed calculation. Optimized the cell with PBE. After initialization, I run a pbe scf using “run_lapw -p -ec 0.0001 -cc 0.001 -NI” Save the result using “save_lapw pbe” In the next step “init_so_lapw” ( took the default parameters, magnetization is 0 0 1) “Init_nl_vdw “ (kernel type 1) “init_mbj_lapw” “run_lapw -p -so -i 1 -NI” “save_lapw mbj” “init_mbj_lapw” Took the selection 2 for surface calculation, and lmbj for potential And finally I run “run_lapw -p -lmbj -so -ec 0.0001 -cc 0.001 -i 999 -NI” And then I save the result using save_lapw lmbj. I want to know whether these are the correct steps for calculating band structure with lmbj potential available in wien2k_23. Thanks in Advance Regards Burhan Ahmed Research Scholar, AUS |
