Dear All,
I ran a piece of code on Google Collab after successfully installing LAMMPS on it using the cmake option. I used the 29th October tar file to do the same.
I am getting an error statement that says ‘unrecognized pair_style ‘reax/c’ is part of the USER-REAXC package which is not enabled in this LAMMPS binary.’ (Snap attached)
I would really appreciate it if anyone can come up with some suggestions for this issue.
You snapshot doesn’t show which command(s) you used to compile LAMMPS.
When you run lmp -h it will give you a summary of command line options but then a list of included settings, packages and individual styles. As the error message indicates, this does not seem to include the USER-REAXC package (now called REAXFF in the most recent LAMMPS version and the online docs) which means that you didn’t specify it when compiling LAMMPS.
I performed the same calculation on LAMMPs 2022, it works well.
however, when I run it using LAMMPs 2023, it will report errors.
Unrecognized pair style ‘reax/c’ is part of the REAXFF package which is not enabled in this LAMMPS binary. (src/src/force.cpp:271)
Last command: pair_style reax/c control.reax_c.cas safezone 66 mincap 1000
if I modify reax/c as reaxff, same error will be reported. [Unrecognized pair style ‘reaxff’ is part of the REAXFF package… …]
Are there someone know how to resolve it?
Thanks in advance.
Best,
Meili
As the error message states, your LAMMPS executable does not include the REAXFF package.
