Research Abstract

In particle methods, high speed computation algorithms on GPU (Graphics Processing Unit) have been developed for fluid and solid dynamics based on the MPS (Moving Particle Simulation) method and for powder dynamics based on DEM (Discrete Element Method). The present algorithms can also be applied to general parallel computers. Its utility is shown by a three-dimensional simulation of tsunami run-up on a real topography.
