1Measurement precision
If parameters of Lennard-Jones potential are determined by operator intuition and experience, then the simulation process is simple to operate, but the accuracy of simulation results deteriorates
Solution Approach 1:
The patent replaces the manual operator-based parameter determination process with an automated computer calculation system. The computer automatically calculates Lennard-Jones potential parameters (ε and σ) by processing molecular structure data and interaction energy information, eliminating the need for operator intuition and experience while significantly improving accuracy.
