phonon calculation with fix phonon command

Hello Dear lammps users
please explain completely.
How can i produce the map.in file and also a binary file for my structure?
Thank you very much.
Best regards
Majid

information about the map.in file including pointers to a software to generate it are in the fix phonon documentation.
and there are pointers to additional information here: https://lammps.sandia.gov/doc/Packages_details.html#pkg-user-phonon
if that is insufficient, you need to contact the author of the USER-PHONON package.

i don’t understand what you are referring to by “binary file of my structure”, so I cannot provide any advice there.
