Keyword descriptions

SECTION_PARAMETERS: enum = HIGH

Lone keyword: SILENT

Usage: silent

Valid values:

• ON

• OFF

• SILENT

• LOW

• MEDIUM

• HIGH

• DEBUG

Level starting at which this property is printed [Edit on GitHub]

ADD_LAST: enum = NO

Usage: ADD_LAST (NO|NUMERIC|SYMBOLIC)

Valid values:

• NO Do not mark last iteration specifically

• NUMERIC Mark last iteration with its iteration number

• SYMBOLIC Mark last iteration with lowercase letter l

If the last iteration should be added, and if it should be marked symbolically (with lowercase letter l) or with the iteration number. Not every iteration level is able to identify the last iteration early enough to be able to output. When this keyword is activated all iteration levels are checked for the last iteration step.

APPEND: logical = F

Lone keyword: T

append the cube files when they already exist [Edit on GitHub]

COMMON_ITERATION_LEVELS: integer = 0

Usage: COMMON_ITERATION_LEVELS

How many iterations levels should be written in the same file (no extra information about the actual iteration level is written to the file) [Edit on GitHub]

FILENAME: string

Usage: FILENAME ./filename

controls part of the filename for output. use __STD_OUT__ (exactly as written here) for the screen or standard logger. use filename to obtain projectname-filename. use ./filename to get filename. A middle name (if present), iteration numbers and extension are always added to the filename. if you want to avoid it use =filename, in this case the filename is always exactly as typed. Please note that this can lead to clashes of filenames. [Edit on GitHub]

LOG_PRINT_KEY: logical = F

Lone keyword: T

Usage: LOG_PRINT_KEY

This keywords enables the logger for the print_key (a message is printed on screen everytime data, controlled by this print_key, are written) [Edit on GitHub]

NGAUSS: integer = 12

Usage: NGAUSS 10

Number of Gaussian functions used in the expansion of atomic (core) density [Edit on GitHub]

STRIDE: integer = 2 2 2

Usage: STRIDE 2 2 2

The stride (X,Y,Z) used to write the cube file (larger values result in smaller cube files). You can provide 3 numbers (for X,Y,Z) or 1 number valid for all components. [Edit on GitHub]

TOTAL_DENSITY: logical = F

Lone keyword: T

Usage: TOTAL_DENSITY {logical}

Print the total electronic density in the case of a GAPW run. This keyword has only an effect, if PAW atoms are present. The default is to print only the soft part of the electronic density and to ignore the hard part. NOTE: The total density in real space might exhibit unphysical features like spikes due to the finite and thus truncated g vector expansion [Edit on GitHub]

XRD_INTERFACE: logical = F

Lone keyword: T

It activates the print out of exponents and coefficients for the Gaussian expansion of the core densities, based on atom calculations for each kind. The resulting core dansities are needed to compute the form factors. If GAPW the local densities are also given in terms of a Gaussian expansion, by fitting the difference between local-fhard and local-soft density for each atom. In this case the keyword TOTAL_DENSITY is set to FALSE [Edit on GitHub]

__CONTROL_VAL: integer = 8

hidden parameter that controls storage, printing,… of the print_key [Edit on GitHub]
