A new contact detection method for arbitrary dilated polyhedra with potential function in discrete element method

Summary Contact detection significantly affects the computational efficiency of discrete element simulations, especially for irregularly shaped elements. The dilated polyhedron is constructed by the Minkowski sum of a dilated sphere and a core convex polyhedron. One of the greatest advantages of usi...
