Hello,users

I searched the previous lammps users usually produce velocity vector and do post-processing with those velocity vectors using Matlab for calculation of phonon density of state.

I would like to calculate the vibrational density of state.I have dumped the velocity(vx,vy,vz)? Could you give me some information how to do the post-processing in details( I know Matlab)?

How can I calculate the VDOS in particular region of my simulation box?

I am grateful if you could reply me.

Thank you

All best
