Amsterdam Modeling Suite


Reactive molecular dynamics

With the specialized atomistic potential in the reactive force field (ReaxFF) you can model chemical reactions in large-scale systems. In collaboration with the van Duin group, SCM has parallelized and significantly optimized the original ReaxFF code. Reactions in complex materials and chemical mixtures totaling hundreds of thousands of atoms can now be modeled on a modern desktop computer.

The ReaxFF module in the Amsterdam Modeling Suite includes many advanced options, including (re)parametrization tools to refine force fields or build new ReaxFF parameter sets. ReaxFF has been used over the past decade in various studies of complicated reactive systems, including combustion chemistry, polymers, nanoparticles, biological systems, surface chemistry, and batteries.

The latest development of ReaxFF, eReaxFF, allows for the explicit treatment of electrons and hence the study of large systems undergoing redox reactions.
