tanks for your answer.
I use meam potential and i want calculate angle distribution for structure.
Can i use LAMMPS for post-processing ? and how?
Because for angle calculate i need to define angle style and Subsequently angle
type define that is problem(define angle type for any atoms)
LAMMPS does not have a compute that calculates
angles. If it did, you could pass its list of angles
to fix ave/histo and get a distribution. An angle
style in LAMMPS is something different - it is used
to define a potential to compute forces on static
triplets of atoms - not what you want. Someone (you?)
would have to write a compute that finds and calculates
angles on arbitrary nearby triplets of atoms.
