Abstract base class for coordination number evaluator
| Type | Visibility | Attributes | Name | Initial | |||
|---|---|---|---|---|---|---|---|
| real(kind=wp), | public | :: | cut | = | -1.0_wp |
Cutoff for the maximum coordination number (negative value, no cutoff) |
|
| real(kind=wp), | public | :: | cutoff |
Radial cutoff for the coordination number |
|||
| real(kind=wp), | public | :: | directed_factor |
Factor determining whether the CN is evaluated with direction if +1 the CN contribution is added equally to both partners if -1 (i.e. with the EN-dep.) it is added to one and subtracted from the other |
|||
| real(kind=wp), | public | :: | kcn |
Steepness of counting function |
