Title:
A multiresolution local-timestepping scheme for particle–laden multiphase flow simulations using a level-set and point-particle approach 
Abstract:
We present a novel storage-and-access approach for Lagrangian particles in a multiresolution local-timestepping framework for multiphase flow simulations. The proposed method applies a block-particle mapping strategy for efficient access of all particles on a specific refinement level while traversing through the multiresolution tree. This allows for extending the local timestepping algorithm with its refinement level-dependent timestep sizes to the evolution of particles, which results in signi...    »
