WebSep 1, 2024 · Reactive MD simulation The MD simulations involving reactive force field, known as reaxFF, were performed in order to simulate the realistic interacting entities in ambient conditions [42]. In addition, in some cases, we carried out the optimization procedure for some oil component with the reaxFF. WebForce field (FF) methods are magnitudes faster than QM methods, and as such can be applied to perform nanosecond-dynamics simulations on large (≫1000 atoms) systems. However, these FF methods can usually only describe a material close to its equilibrium state and as such cannot properly simulate bond dissociation and formation. impulse meaning class 11
