contact/atom

Hi Lammps users,

I shall be thankful if anyone explained me how to output average contact number per atom into a file.

I just used following two commands in my lammps input file… The ‘compute’ command for computation of the contact per atom and I have used the ‘fix’ command to write the output into a file.

compute 5 all contact/atom

fix 5 all ave/atom 100 100000 10000000 c_5 ave one file zperatom.dat

But the fix command gave an error saying that

ERROR: Illegal fix ave/atom command (…/fix_ave_atom.cpp:113)

If somebody can help me, that would be a great help for me.

Thanks.

Nira.

​yes, and it is a well deserved error.​ ​you need to explain where in the
documentation of the fix ave/atom command are the flags "one" "ave" and
"file" mentioned? i don't see them here:
http://lammps.sandia.gov/doc/fix_ave_atom.html​

that goes without saying.
