Hi

Have Lammps Sutton-Chen potential and coefficients?

Hi

Have Lammps Sutton-Chen potential and coefficients?

what you see (in the manual) is what you get:

in other words: no, not unless you implement it.

thanks for your attention.
This potential is not there but it is used for simulation of most
metals such as Cu,Au,Ag,Ni,Pt,Pd, .....!!!!!

With the best regards,
Mohsen.

no reason to use that many exclamation marks.
different people have different preferences. very
apparently, the folks that prefer using LAMMPS
didn't feel as passionate about it, or preferred some
other method.

in any case, have a look at the following URL
and feel free to get your hands dirty. :wink:

http://lammps.sandia.gov/doc/Section_modify.html

if you care so much about having these available,
it won't be much of a bother to spend the time. :slight_smile:

cheers,

I'm now remembering that Sutton-Chen is just
a variant of EAM? So possibly what you
want are simply EAM potential files that
were created using the Sutton-Chen formalism?

In which case you can use the pair_style eam
in LAMMPS. You just need the potential
files for the materials you want. There are lots
of EAM-formatted files (typically in DYNAMO
format, which is what LAMMPS reads in) at
various sites on the Internet. Check the
doc/pair_eam.html file in LAMMPS for pointers
to a few of them. And look in the potentials
dir in LAMMPS - there are already EAM files
for many elements.
