Contact interaction and contact detection remain key components of any discontinua simulations. The methods of discontinua include: Combined Finite-Discrete Element Method (FDEM), Discrete Element Method (DEM), Molecular Dynamics (MD), etc. In recent years, a number of contact detection algorithms have been developed, such as: Munjiza-Rougier (MR), MunjizaRougier-Schiava (MR-S), Munjiza-No Binary Search (NBS), Balanced Binary Tree Schiava (BBTS), 3-D Discontinuous Deformation Analysis (DDA), and many others. In this work a numerical comparison is conducted of certain algorithms often used in FDEM foron bodies of the same size. These include MR, MR-S, NBS and BBTS algorithms.
