ABSTRACT:
Particle-based methods are being increasingly adopted for modelling realistic systems in a wide range of applications. Here we present two particle-based analysis tools: Smoothed Particle Hydrodynamics (SPH) and Discrete Element Method (DEM). SPH is a mesh-free computational method for modelling continuum based systems and processes, whereas DEM is primarily suitable for simulating dry particulate/granular systems. These techniques offer many advantages over conventional mesh-based techniques (e.g. FEM), such as modelling large deformations and tracking history dependent properties.

Meshless methods such as, SPH and DEM can play a major role in understanding flow and deformation behaviour of complex systems. This can lead to improved design of equipments and processes, leading to efficient systems, higher productivity and product quality, effective operation and maintenance procedures. The effectiveness of SPH and DEM in gaining fundamental insights of physical problems is illustrated through a variety of industrial applications.
