Reactive md-force field
http://kiff.vfab.org/reax WebReactive MD methods use a force field description which is ‘trained’ to reproduce reactions determined from quantum mechanical calculations and experimental data. A class of such methods uses concept of bond-order to represent the forces between interacting atoms in a chemical system. Typical examples of such force descriptions include ...

Did you know?
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… WebParametrization of the Reactive MD Force Field for ZnO-H Systems K. S. Shefova, M. Stepanovab, S. N. Kotriakhovac Published 2024 Computer Science We describe a procedure of optimizing the molecular dynamic force field for Zn-O-H chemical systems by means of a new parallel algorithm of a multifactorial search for the global minimum.
