Abstract:
Computational geometry is a foundational component of Monte Carlo particle transport, influencing simulation performance, robustness, and the complexity of systems that can be represented. As modeling demands grow and computing architectures evolve, new opportunities are emerging to rethink how geometry is represented and traversed in particle transport applications. This talk will examine the current state of computational geometry in OpenMC and discuss ongoing efforts to expand its capabilities through new software infrastructure, advanced geometric representations, and hardware-accelerated algorithms. Looking beyond current developments, the talk will explore emerging research directions at the intersection of
computational geometry, computer graphics, and scientific computing, highlighting opportunities to improve efficiency, enable new classes of analysis, and broaden the role of geometry in high-fidelity nuclear simulation.
