Parameters for calculating force¶
Parameters here are for calculating atomic force. The atomic force is defined as the negative derivative of the total energy with respect to the displacement of atomic position.
calculation.force.decomposed¶
key word |
: |
calculation.force.decomposed |
possible values |
: |
1, true, 0, false |
default value |
: |
false |
description |
: |
If true, the total force will be decomposed into |
several terms and the value of each term is given. If |
||
false, only the total force is given. |
||
an example |
: |
calculation.force.decomposed = true |
calculation.force.movingAtoms¶
key word |
: |
calculation.force.movingAtoms |
possible values |
: |
integer array |
default value |
: |
all atoms in the central cell |
description |
: |
The 3*n force components corresponding to the atoms |
listed in the movingAtoms will be calculated, and the |
||
other force components will be given as NaN or zero. |
||
Please note that the order of the atoms has been listed |
||
in the output file Atoms.txt, which may be different |
||
from original input. |
||
an example |
: |
calculation.force.movingAtoms = [10:291] |
