This paper presents a parallel implicit algorithm to simulate and analyse the dynamic behaviour of solid particles on backward acting grates. The Discrete Element Method (DEM) with implicit integration is applied to model the dynamics of solid particles and a domain decomposition technique is used for implementing the parallel algorithm. The findings suggest that the combination of the implicit method and domain decomposition techniques is quite efficient in simulating the dynamics of granular particles. Qualitative comparison of the numerical and experimental results indicates the capability of the proposed methodology to analyse the residence time behaviour of solid particles on a backward acting grate. The parallel performance measured on a cluster with 1 Gigabit Ethernet (GbE) connection shows that the implemented parallel algorithm can achieve a speedup of 6.55 and efficiency of 82% using eight processors.
