General
*******

ReaxFF is an engine for modeling chemical reactions with atomistic
potentials based on the reactive force field approach developed by
Prof. Adri van Duin and coworkers. SCM has modernized, parallelized
and greatly optimized the original ReaxFF program.


What's new in ReaxFF 2020
=========================

ReaxFF is available in the AMS driver as one of the engines, which
means that all tasks that can be performed with the AMS driver are
also available for ReaxFF. However, not all tasks from the classic
ReaxFF standalone program are available in the ReaxFF AMS engine, so
in the 2020 release of the Amsterdam Modeling Suite, the standalone
ReaxFF program and the ReaxFF engine coexist. **The graphical user
interface program AMSinput only sets up ReaxFF jobs as an engine to
the AMS driver**.

For more information, see ReaxFF Engine Features Vs. Old Standalone
Program.

**Other new features:**

* 0D, 1D, and 2D periodicity

* Tapered bond orders

* Charge constraints

Note:

  Development of the old standalone ReaxFF program has stopped.
