Object Kinetic Monte Carlo (OKMC): A Coarse-Grained Approach to Radiation Damage

Reference work entry


Object kinetic Monte Carlo (OKMC) approaches allow one to explicitly coarse grain atomic processes to simulate the evolution with time of the system/microstructure. This class of methods is quite versatile and can be used to model different processes where the motion of atoms in a given microstructure and their interaction with sinks and traps of the microstructure lead to changes such as phase transition or modification. In this chapter, the method is presented as applied to radiation damage modeling. Along with a description of the technique, we discuss the different pathways possible to couple OKMC with smaller- as well as larger-scale methods and conclude with a brief enumeration of what we believe are the issues for future development.
