A Fusion-Oriented Neutronics Modeling and Multiphysics Coupling System

A system has been developed to fulfill the entire coupled multiphysics analysis cycle for the design and analysis of complex fusion reactor components. It provides advanced modeling capability for converting computer-aided-design geometries to Monte Carlo (MC) geometries by employing constructive solid geometries and unstructured meshes. It also realizes the generic multiphysics coupling of the MC neutronics, computational fluid dynamics, and finite element thermal and structural analyses. This system is a seamless, extensible, and generic system that has been intensively verified for fusion applications.
