Introduction -- Superquadric DEM model based on continuous function representation -- Multi-superquadric and poly-superquadric DEM models -- Smooth polyhedral model based on Minkowski sum algorithm -- Arbitrarily shaped DEM model based on level set method -- High performance computation and DEM software development -- DEM analysis of flow characteristics of non-spherical particles.

This book focuses on discrete element methods for arbitrarily shaped granular materials, including super-quadric models, spherical harmonic functions and level set methods, and numerical analysis of the flow characteristics of non-spherical granular materials. This book is used as a reference book for scientific researchers engaged in dynamic analysis of granular materials and optimal design of equipment structures in the fields of engineering mechanics, applied physics, mechanical engineering, and chemical engineering, as well as for graduate students or senior undergraduates of related majors in institutions of higher education. .
