I have been trying to use the AI-REBO potential. I have written an input script which has a hybrid AI-REBO/EAM/LJ potential.
boundary p p p
pair_style hybrid lj/cut 10.0 eam/fs airebo 3.0 1 1
pair_coeff * * airebo CH.airebo C C C
pair_coeff * * eam/fs Fe_mm.eam.fs NULL NULL Fe
When I run the script, the log file tells me:
“ERROR: Invalid pair style”
right after the line: “pair_style hybrid lj/cut 10.0 eam/fs airebo 3.0 1 1”.
I have used the eam/fs and lj/cut pair_styles in the past and had no problems. So, I am
pretty sure the reason for the error message is the AI-REBO potential. Is there anything that I am missing?
I found in the documentation that :
“This pair style is part of the “manybody” package. It is only enabled if LAMMPS was built with that package (which it is by default).”
However, I built LAMMPS (06/22/2007 version) in the default mode and so this should not be a problem.
It will be very helpful to have some input.
