[lammps-users] Problem with ave/time and ave/chunck

Dear all,


I am having a problem in outputting data per chunk. The problem is that the generated output files (generated by either ave/time or ave/chunk commands) are empty although they shouldn’t be. I am using LAMMMPS version 31-March-2017.


The input code is given below:



read_restart Restart.file

change_box all z final -57.5 137.5


pair_style lj/cut/coul/long 13

pair_modify tail yes

kspace_style pppm 1.0e-5


neighbor 2.0 bin

neigh_modify delay 10 check yes


region EDGE block 1.2 38.5 1.2 38.5 77.5 78.5

delete_atoms region EDGE mol yes


compute HMOL all chunk/atom molecule

compute MSD all msd/chunk HMOL


fix TEMP all nvt temp 300 300 8


fix 1 all ave/time 1 1 1 c_MSD[*] file MSD.out mode vector

fix 2 all ave/chunk 1 1 1 HMOL vz file tmp.vz


timestep 2

run 100


Any idea on why this happens?


Thank you very much,

M. Hasan
