Abstract: Casting, solidification, and the behavior of dry, saturated, and partially saturated granular media are examples of interesting and important problems in multiple areas of civil, mechanical, and chemical engineering. For interacting particle-fluid systems, the Discrete Element Method (DEM) and Lattice-Boltzmann Method (LBM) provide valuable high-resolution numerical models. Their main issue is high computational demand, which can be addressed by use of HPC resources. This work demonstrates the use of MPI-parallelized LBM and DEM models to accelerate research in solidification and macroscopic behavior of dry and saturated granular media. Large scale parallel simulations of dendritic growth, the calibration-chamber cone penetration test, and a parametric study of shear thickening in granular suspension were performed. Use of HPC dramatically reduced the computational time for these studies and provided high-resolution representation of physical experiments.
