Hi everyone,

Im trying to do a geometric optimization of BCN-nanosheets to calculate their electronic structure. I would like to known which are the best vasp parameter (INCAR and KPOINTS) for this kind of calculation. I would like to know how to generate the POSCAR file from pdb file, because using the program VESTA I can generate this file, but the system in the POSCAR file isn?t the same.
I need an example of POSCAR file, INCAR file and KPOINTS for this kind of system, because is my first time using vasp. Is it possible to do this kind of calculation? Please help meeeee... My system is (I would like to do the POSCAR file):
