Output file format error (dipole)

LAMMPS LAMMPS General Discussion

Dear LAMMPS Users

I am trying to extract dipole information to do post-processing using the following setup:

compute            1 all property/atom q xu yu zu
variable           dipolex atom c_1[1]*c_1[2]
variable           dipoley atom c_1[1]*c_1[3]
variable           dipolez atom c_1[1]*c_1[4]
compute            2 all reduce sum v_dipolex
compute            3 all reduce sum v_dipoley
compute            4 all reduce sum v_dipolez
variable           totaldipolex equal c_2
variable           totaldipoley equal c_3
variable           totaldipolez equal c_4
variable           mytime equal step*dt
fix                printdipole all ave/time 1 1 2 v_mytime v_totaldipolex v_totaldipoley v_totaldipolez file dipole.txt mode scalar format %.10f
run 100000
unfix 1

However, the data is too close together, the numbers are printed in the file without spaces, any suggestions to detect the error?

# Time-averaged data for fix printdipole
# TimeStep v_mytime v_totaldipolex v_totaldipoley v_totaldipolez

This is self-inflicted and LAMMPS is just doing what you are asking for.
You set the output format to %.10f. That requests the precision, but no space.
So you need to change it to something like %15.10f or " %.10f".

Thanks professor Axel

BTW: this complex piece of input can be simplified to:

compute            1 all dipole
variable           mytime equal time
fix                printdipole all ave/time 1 1 2 v_mytime c_1[*] file dipole.txt mode scalar format %15.10f
