WebDuring the NEB path optimization, a climbing image algorithm is used to drive the highest-energy image in the path to the transition state (unless the Climbing option is set to False). Be aware that NEB is a computationally … WebThe climbing image nudged elastic band (CI-NEB) method was applied to study the diffusion of a single K ion in the PEDOT and RP by calculating the variation in energy as K + moves between equivalent interstitial sites. The diffusion coordinate is calculated based on the cumulative sum of the trajectory length of all atoms in the structures.
