Optimal Spatial Subdivision method for improving geometry navigation performance in Monte Carlo particle transport simulation

Convex-based void filling method for CAD-based Monte Carlo geometry modeling

“…There are two ways of subdivision, the uniform subdivision and non-uniform subdivision (Chen, 2015). The Quality-based spatial Subdivision (QS) in CVF method adopts the uniform scheme to divide the problem space as the non-uniform subdivision costs much more computing time.…”

CAD-based hierarchical geometry conversion method for modeling of fission reactor cores

“…It was clear that the new method saved a lot of modeling time while ensuring the accuracy compared with conventional method and the reference results simulated by MCNP code. The SuperMC code had developed many methods to improve geometry navigation performance (Chen et al, 2015). Realistically, from the simplest GH-tree data structure, the calculation module of SuperMC could get the hierarchical relations and the lists of neighbors.…”
