Steps to run: Requires a VASP POSCAR file in the current 8. Simple constraint applied: the distance between two atom cores are forced to be Writes label, scalefactor, unitcell, # of various kinds of atoms, positions in cartesian or scaled coordinates (Direct), and constraints to file. predictor_corrector_preamble Poscar. Wang, N. 3 documentation以下为原文 VASP计算经常碰到一件事情就是固定POSCAR的原 Is it possible to direct VASP to read a POSCAR-xyz file instead of reading the default POSCAR? For example, I want to run VASP in the Quantum ESPRESSO format: $/PW. The POSCAR/.
