Dear LAMMPSers:
I have some questions while using LAMMPS.
At the beginning, I want to say that in my input script , there is a line of
"units metal"
as we all know:
For style metal, these are the units:
* distance = Angstroms
* time = picoseconds
* mass = grams/mole
* velocity = Angstroms/picosecond
* force = eV/Angstrom
... ...
In the web page below:
http://lammps.sandia.gov/doc/compute_stress_atom.html
In that following formula, Sab is the sum of 3 terms: m*v*v, r_ij*Fp,
R_ij*Fb
In my opinion, the unit of term:"m*v*v" is the same with "r_ij*Fp", both are
"eV"
But the unit of mass for style metal is "grams/mole".
How can we get "eV" for "m*v*v".
If this assume is incorrect, what the right one should be ?
Thanks for any reply!
