Discrete Element Method

This course delves into essential aspects of particle dynamics and simulation. Core elements include formulating modeling strategies, employing conceptual and numerical models, and understanding granular material behavior. Topics encompass DEM classification, contact detection, and interaction force-displacement and friction laws. Algorithms for solving motion equations, along with simulation tool introductions (e.g., Yade, LIGGGHTS),will be covered, supplemented by practical insights and applications. Practical exercises in both 2D and 3D scenarios offer hands-on experience, enhancing students' abilities to simulate particle systems effectively and apply these principles in diverse contexts.
