IMPLEMENTATION OF THE DISCRETE ELEMENT METHOD USING RECONFIGURABLE COMPUTING (FPGAS)

Abstract eng:
The Discrete Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles. They can be bonded together to represent rock or remained unbonded to represent soil. The DEM is computationally very expensive, but can benefit from the properties of reconfigurable computing. This paper presents the design of a dedicated hardware architecture for the DEM with single sized 2-D particles implemented on a Field Programmable Gate Array (FPGA). Its performance is compared with an optimized Software version running on a state of the art PC and speed up of up to a factor of 60 was achieved.
