“Lattice Boltzmann Methods on the way to exascale”
by Ulrich Ruede, Cerfacs, Universität Erlangen-Nuernberg
Lattice Boltzman methods have become popular as an alternative method to simulate complex flows on parallel computers. One of their strengths is in simulating multiphase systems such as bubbly flows or foams. When coupled with methods to model granular objects, the LBM can also be used to simulate fluids with a suspended particulate phase. In this talk we will report on our scalable, adaptive LBM implementation that can reach up to a trillion (10^12) fluid cells on current Peta-Scale supercomputers. The practical relevance of these methods will be illustrated with simulations of an additive manufacturing (3D-printing) process.
