Rate Theory: Cluster Dynamics, Grouping Methods, and Best Practices

Abstract

Cluster dynamics is a mean field method which is used to simulate the evolution of defect clusters in materials under aging and irradiation conditions. Its popularity is due to the simplicity of the underlying “cluster gas” model, which is able to simulate accurately and efficiently dilute cases, provided it is carefully parametrized. In this chapter cluster dynamics formalism is reviewed. Parametrization of cluster dynamics models and numerical schemes to efficiently solve cluster dynamics equations are discussed.
