DualSPHysics is a weakly compressible smoothed particle hydrodynamics (SPH) Navier–Stokes solver initially conceived to deal with coastal engineering problems, especially those related to wave impact with coastal structures. Since the first release back in 2011, DualSPHysics has shown to be robust and accurate for simulating extreme wave events along with a continuous improvement in efficiency thanks to the exploitation of hardware such as graphics processing units for scientific computing or the coupling with wave propagating models such as SWASH and OceanWave3D. Numerous additional functionalities have also been included in the DualSPHysics package over the last few years which allow the simulation of fluid-driven objects. The use of the discrete element method has allowed the solver to simulate the interaction among different bodies (sliding rocks, for example), which provides a unique tool to analyse debris flows. In addition, the recent coupling with other solvers like Project Chrono or MoorDyn has been a milestone in the development of the solver. Project Chrono allows the simulation of articulated structures with joints, hinges, sliders and springs and MoorDyn allows simulating moored structures. Both functionalities make DualSPHysics especially suited for the simulation of offshore energy harvesting devices. Lately, the present state of maturity of the solver goes beyond single-phase simulations, allowing multi-phase simulations with gas–liquid and a combination of Newtonian and non-Newtonian models expanding further the capabilities and range of applications for the DualSPHysics solver. These advances and functionalities make DualSPHysics an advanced meshless solver with emphasis on free-surface flow modelling.

DualSPHysics是一种可压缩性较差的平滑粒子流体动力学（SPH）Navier-Stokes求解器，最初设计用于处理海岸工程问题，尤其是与波浪对海岸结构的影响有关的问题。自2011年首次发布以来，DualSPHysics在模拟极端海浪事件方面表现出强大而准确的特性，并且由于对硬件的利用（例如用于科学计算的图形处理单元或与海浪传播模型的耦合），在模拟效率方面不断提高。作为SWASH和OceanWave3D。在过去的几年中，DualSPHysics软件包中还包含了许多附加功能，这些功能可以模拟流体驱动的对象。离散元素方法的使用已使求解器能够模拟不同物体（例如，滑动岩石）之间的相互作用，从而提供了一种独特的工具来分析泥石流。此外，最近与其他求解器（如Project Chrono或MoorDyn）的耦合已成为求解器开发中的一个里程碑。Chrono项目可以模拟带有关节，铰链，滑块和弹簧的铰接结构，而MoorDyn可以模拟系泊的结构。这两个功能使DualSPHysics特别适合用于海上能源收集设备的仿真。最近，求解器的当前成熟状态超出了单相模拟的范围，允许使用气-液以及牛顿模型和非牛顿模型的组合进行多相模拟，从而进一步扩展了DualSPHysics求解器的功能和应用范围。这些先进的功能使DualSPHysics成为高级的无网格求解器，并着重于自由表面流动建模。
