Recently, the research group led by Prof. Liu Changsong from Institute of Solid State Physics (ISSP), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) developed a set of software for simulating the evolution of displacement damage in polycrystalline metals at across time and space scales, which was named object kinetic Monte Carlo-lattice kinetic Monte Carlo (OKMC-LKMC) hybridization simulation software.
