angle_style gaussian command¶
angle_style gaussian angle_coeff 1 300.0 2 0.0128 0.375 80.0 0.0730 0.148 123.0
The gaussian angle style uses the potential:
This analytical form is a suitable potential for obtaining mesoscale effective force fields which can reproduce target atomistic distributions (Milano) The following coefficients must be defined for each angle type via the angle_coeff command as in the example above, or in the data file or restart files read by the read_data or read_restart commands:
T temperature at which the potential was derived
\(n\) (integer >=1)
This angle style can only be used if LAMMPS was built with the EXTRA-MOLECULE package. See the Build package doc page for more info.
