Name: output file of the Vienna Ab initio Simulation Package (VASP)
Extension: none (the file must be named OUTCAR by VASP)
Specification: VASP documentation
Visualization programs: none
Atomsk can read files in the OUTCAR format (as specified in VASP versions 4.x and 5.x) only in the mode "--one-in-all". This mode reads all the configurations from the OUTCAR file, and writes each of them in a separate file. Forces acting on atoms are also read from the OUTCAR file, and will be written if the output format supports it.
Note that the OUTCAR file contains several configurations, only if VASP performed ionic relaxation or molecular dynamics (IBRION≥0). Otherwise, it only contains information about electronic states which Atomsk does not support.
Atomsk cannot write file in OUTCAR format.
atomsk --one-in-all OUTCAR cfg
This will read the file OUTCAR, and write each configuration into a separate file in the CFG format, named OUTCAR_0.cfg, OUTCAR_1.cfg, OUTCAR_2.cfg, and so on. Forces acting on atoms will also be imported, and written into the CFG files.
atomsk --one-in-all OUTCAR vesta
This will read the OUTCAR file, and write configurations in VESTA format for visualization.
