Brief Introduction of the Output Files

The following files are the central output files for ABACUS. After executing the program, you can obtain a log file containing the screen output, more detailed outputs are stored in the working directory OUT.suffix (Default one is OUT.ABACUS). Here we give some simple descriptions.

INPUT

Different from INPUT given by the users, OUT.suffix/INPUT contains all parameters in ABACUS.

Note: OUT.suffix/INPUT contain the initial default of ABACUS instead of the real parameters used in calculations. If you want to figure out the real parameters used in calculations, you can open OUT.suffix/runing_scf.log and research corresponding parameter you are interested.

For a complete list of input parameters, please consult this instruction.

running_scf.log

running_scf.log contains information on nearly all function calls made during the execution of ABACUS.

KPT

This file contains the information of all generated k-points, as well as the list of k-points actually used for calculations after considering symmetry.

istate.info

This file includes the energy levels computed for all k-points. From left to right, the columns represent: energy level index, eigenenergy, and occupancy number.

Below is an example istate.info:

STRU_SIMPLE.cif

ABACUS generates a .cif format structure file based on the input file STRU, facilitating users to visualize with commonly used software. STRU_READIN_ADJUST.cif is the structure after considering symmetry.

warning.log

The file contains all the warning messages generated during the ABACUS run.
