energy contributions

Dear Lammps users,
I have a question about energy contributions printed out to the output file. I have checked all the files (and routines) and recalculated different energy contributions. All the outputs are the same as what is calculated at each function except the long-rang coulombic interaction (I use ewald for longrange interactions). Is there any coefficient which is multiplying to the long-range energy contribution before printing.

Any help/suggestion is greatly appreciated
Emily

dear emily,

Dear Lammps users,
I have a question about energy contributions printed out to the output file.
I have checked all the files (and routines) and recalculated different
energy contributions. All the outputs are the same as what is calculated at
each function except the long-rang coulombic interaction (I use ewald for
longrange interactions). Is there any coefficient which is multiplying to
the long-range energy contribution before printing.

please state which version of lammps exactly you are using
and provide a more tangible example and description of how
you determine the discrepancy.

there should be none, but that requires that accounting and
checking is done correctly.

thanks,

It's possible that LAMMPS partitions the energy
between short-range Ecoul and long-range energy
differently than other codes. What should be
the same is if you sum the 2 Coulombic portions
and compare to the total Coulombic energy.
