Abstract: A fully Lagrangian mesh-free method, Smoothed Particle Hydrodynamics (SPH) method, is applied to model the flow of self-compacting concretes (SCC) in three dimensions. The present SPH model solves the weakly compressible Navier–Stokes equations and the hardware acceleration for SPH calculations was implemented using the novel computing architectures called Graphics Processing Units (GPUs) based on the Compute Unified Device Architecture (CUDA).The proposed method has validated by comparing the numerical results with theoretic solution in the literature. Both the achieved speed-ups and the quantitative agreement with analytical solution suggest that the SPH methods on GPU with CUDA can be used to model the flow of self-compacting concretes with efficiency and reliability.
