Keyword descriptions

ATOMS: integer

Usage: ATOMS 1 3 6

Atoms’ index on which apply the constraint [Edit on GitHub]

DISTANCES: real = [internal_cp2k]

Usage: DISTANCES {real} {real} {real}

The constrained distances’ values. [Edit on GitHub]

EXCLUDE_MM: logical = F

Lone keyword: T

Usage: EXCLUDE_MM

Does not apply the constraint to the MM region within a QM/MM calculation [Edit on GitHub]

EXCLUDE_QM: logical = F

Lone keyword: T

Usage: EXCLUDE_QM

Does not apply the constraint to the QM region within a QM/MM calculation [Edit on GitHub]

INTERMOLECULAR: logical = F

Lone keyword: T

Usage: INTERMOLECULAR

Specify if the constraint/restraint is intermolecular. [Edit on GitHub]

MOLECULE: integer

Aliases: MOL

Usage: MOL {integer}

Specifies the molecule kind number on which constraint will be applied. MOLECULE and MOLNAME keyword exclude themself mutually. [Edit on GitHub]

MOLNAME: string

Aliases: SEGNAME

Usage: MOLNAME {character}

Specifies the name of the molecule on which the constraint will be applied. [Edit on GitHub]
