PCDAT: Difference between revisions

Revision as of 08:38, 17 June 2019

The PCDAT file contains the pair correlation function. For dynamic simulations (IBRION $\ge$ 0) an averaged pair correlation is written to the file (see also NBLOCK, KBLOCK, NPACO and APACO).

A sample output of the PCDAT file for a 64 atom cell of Si looks as follows:

   1  64   1   0  0.2002283E+02  0.2000000E+04

Here is the description of each line:

Line 1: 1 (fixed output), number of ions, 1 (fixed output), 0 (fixed output), unit cell volume divided by number of atoms, temperature.
Line 2: CAR (fixed output).
Line 3: Header of INCAR file (the tag SYSTEM).
