摘要：
In this paper we propose a dual-time stepping scheme for the Smoothed Particle Hydrodynamics (SPH) method. Dual-time stepping has been used in the context of other numerical methods for the simulation of incompressible fluid flows. Here we provide a scheme that combines the entropically damped artificial compressibility (EDAC) along with dual-time stepping. The method is accurate, robust, and demonstrates up to seven times better performance than the standard weakly-compressible formulation. We demon-strate several benchmarks showing the applicability of the scheme. In addition, we provide a completely open source implementation and a reproducible manuscript. (c) 2021 Elsevier Ltd.
