Hi, you may change the script to
pair_coeff allegro * * MLFF.pth Pt Pd
pair_coeff lj/cut 1 2 1 1.1 2.8
You are correct, you have to specify the pair_style as well, that was my mistake.
Correct code block looks like this for future reference. The atom range has to come first.
pair_style hybrid/overlay allegro lj/cut 2.5
pair_coeff * * allegro MLFF.pth O H
pair_coeff 1 2 lj/cut 1 1.1 2.8
Glad this worked, thanks @shuhaom for responding.
Also for future reference there is support inside nequip
for adding pair potential terms:
Will this provide the terms to include in LAMMPS or are they included in the model file? An example of how to actually train/run with LAMMPS using this would be very helpful. I am using the stress branch of pair_allegro currently.
This will include them in the Allegro .pth
file and you will not need to use hybrid/overlay
. You will, of course, need to provide in the original Allegro YAML the LJ parameters. (For ZBL no parameters are required; if you are just looking to have a core repulsion term you can try that first; we used it successfully, for example, in https://arxiv.org/abs/2304.10061.)
minimal_pair.yaml
linked above is an example of using ZBL and the required model_builders
.
I expect to be able to mix Allegro and other pair styles as follows in LAMMPS.
When I do this I get the following error
I am guessing this is caused by Allegro not being supported in pair_hybrid with Kokkos? Is this something easy to resolve?
