Abstract Scope |
Molecular dynamics is evolving as an important tool in nuclear energy applications. Among the uses of molecular dynamics in nuclear energy is studying the thermophysical properties of new alloys under irradiation and high temperatures. Discrepancies in calculated material properties have been reported in many areas in molecular dynamics due to inadequate simulation times and inconsistent assessments of convergence. We adapted information theory methods that were previously used in Monte Carlo neutron transport in nuclear reactors to molecular dynamics allowing for reliable assessments of convergence for different types of non-equilibrium molecular dynamics simulations. In this work, various formulations of information entropy are investigated and applied to radiation damage simulations and lattice thermal conductivity calculations. The method has also been demonstrated to be applicable to both solids and fluids. |
