INPUT FILE DESCRIPTION
|
|
|
|
Program: cppp.x / CP / Quantum ESPRESSO (version: 7.4)
|

------------------------------------------------------------------------
|
|
|
|
|
|
=============================================================================
|
|
CP Post-Processing code (cppp.x)
|
|
=============================================================================
|
|
|
|
The cppp.x code is an utility that can be used to extract data from the CP
|
|
restart and CP trajectory files.
|
|
|
|
INPUT:
|
|
=====
|
|
|
|
the program read the input parameters from the standard input or from
|
|
any other file specified through the usual "-input" command line flag.
|
|
The input parameters, in the input file, should be specified in the inputpp
|
|
namelist follow:
|
|
|
|
&INPUTPP
|
|
...
|
|
cppp_input_parameter
|
|
...
