[lammps-users] reaxff

Hello all
When I run reax in the example,it said that the pair_style is not valid.My lammps is the latest version. Haven’t the reax force field been included into lammps ,though it exists in the manual ?
By the way , I want to know if it’s true that only reactive forcefield can apply to reaction . Besides reaxff , are there any other force fileds can describe the formation of bond ?
Can the famous universal force field (UFF) be used to study reaction ?
Best regards

Check the Section_start doc page for building with optional pacakges. ReaxFF
is in the “reax” package. You have to first build the lib/reax library, then
include the package in the LAMMPS build.
