This paper presents a brief review of grand challenges of Smoothed Particle Hydrodynamics (SPH) method. As a meshless method, SPH can simulate a large range of applications from astrophysics to free-surface flows, to complex mixing problems in industry and has had notable successes. As a young computational method, the SPH method still requires development to address important elements which prevent more widespread use. This effort has been led by members of the SPH rEsearch and engineeRing International Community (SPHERIC) who have identified SPH Grand Challenges. The SPHERIC SPH Grand Challenges (GCs) have been grouped into 5 categories: (GC1) convergence, consistency and stability, (GC2) boundary conditions, (GC3) adaptivity, (GC4) coupling to other models, and (GC5) applicability to industry. The SPH Grand Challenges have been formulated to focus the attention and activities of researchers, developers, and users around the world. The status of each SPH Grand Challenge is presented in this paper with a discussion on the areas for future development.

本文简要介绍了平滑粒子流体动力学（SPH）方法的巨大挑战。作为一种无网格方法，SPH可以模拟从天体物理学到自由表面流，再到工业中复杂的混合问题的广泛应用，并取得了显著成就。作为一种年轻的计算方法，SPH方法仍需要开发以解决阻止更广泛使用的重要元素。SPH研究和工程国际社区（SPHERIC）的成员领导了这项工作，他们确定了SPH大挑战。SPHERIC SPH大挑战（GC）分为5类：（GC1）收敛性，一致性和稳定性，（GC2）边界条件，（GC3）适应性，（GC4）与其他模型的耦合以及（GC5）对行业的适用性。SPH大型挑战赛旨在吸引全球研究人员，开发人员和用户的注意力和活动。本文介绍了每个SPH挑战赛的状况，并讨论了未来的发展领域。
