WebOct 1, 2024 · The results show that the simplified model is a decent approximation against PCFF and CVFF force fields, as shown in Fig. 10. During the simulation, for atomic interactions not included in PCFF and CVFF force fields, the force field parameters from the most similar atomic interactions are used as replacements. WebJul 1, 2013 · Initial modeling experiments suggested that PCFF and DREIDING force fields were too unstable to describe systems consisting of a sodium polyacrylate polymer and a calcite surface. Thus, only CVFF, COMPASS and UNIVERSAL force fields were used in further MD simulations. 3.4.1. The effect of orientation and molecular weight
