ReaxFF (for “reactive force field”) is a bond order-based force field developed by Adri van Duin, William A. Goddard, III, and co-workers at the California Institute of Technology. One of its applications is molecular dynamics simulations. Whereas traditional force fields are unable to model chemical reactions because of the requirement of breaking and forming bonds (a force field's functional form depends on having all bonds defined explicitly), ReaxFF eschews explicit b… the assistant engineerWebJun 4, 2015 · Abstract Generating a reactive force field for a given chemical reaction is turned from a many-months project for experts into a task of a few hours for a non-specialist, by joining the newly developed quantum-mechanically derived force field (QMDFF) and Warshel's time-tested empirical valence bond (EVB) idea. the assistant engineer familyWebA new ReaxFF reactive force field has been developed for water-electrolyte systems including cations Li+, Na+, K+ and Cs+, and anions F-, Cl- and I-.
