Seventy years after the Smoothed Particle Hydrodynamics(SPH)method was created,there was the need to use the solid limit to keep the domain particles of a certain region.This boundary’s treatment is usually done with the use of force derived from potential Lennard-Jones.In our paper,a new boundary treatment technique is presented.Now,we use the Coulomb force to exert a repulsive force on the border to avoid outgoing particles leaving the simulation domain.To test this new technique,the problem of dam break and sloshing was simulated.©2018 Shanghai Jiaotong University.Published by Elsevier B.V. 展开更多
