Tree codes and sort-and-sweep algorithms for neighborhood computation: A cache-conscious comparison
Dominik Krengel, Yuki Watanabe, Ko Kandori +2
Neighborhood algorithms may take a considerable percentage of computer time in discrete element methods (DEM). While the sort-and-sweep algorithm is ideal in some ways, as it only…

Tree Code Based Neighborhood Algorithms for Discrete Element Methods
Yuki Watanabe, Dominik Krengel, Hans-Georg Matuttis
We report our experiences for the development of a neighborhood algorithm implemented via tree-codes to optimize the performance of a discrete element method (DEM) for convex polyt…
