This paper presents a review of recent progress made towards the applications of the meshfree particle methods (MPMs) for solving coupled fluid-structure interaction (FSI) problems. Meshfree methods are categorized based on their mathematical formulation and treatment of computational data points. The advantages and limitations of these methods, particularly related to FSI applications, have been identified. A detailed account of salient work related to the FSI problems involving complex geometries, viscous flows, and large structural deformations has been presented and the benchmark solutions are identified for future research. Compared to their mesh-based counterparts, MPMs are found better suited in negotiating moving boundaries and complex geometries, features that are the hallmark of FSI problems. However, the biggest challenge to their wider acceptability is their implementation and programming complexity, higher computational cost, and lack of commercial software packages. So far, meshfree methods have mostly been limited to applications, where conventional methods show limited performance. Owing to its promising growth potential, partitioned FSI is the prime emphasis of this paper. Various aspects of partitioned FSI have been identified and classified for meshfree FSI problems, which include problem formulation strategies, domains discretization approaches, solver coupling methodology, interface treatment, benchmark problems, computational load, and availability of commercial software. Furthermore, various challenges involved in employing MPMs for FSI have also been identified and discussed along with the state-of-the-art techniques used in meshfree methods and FSI applications, and a future way forward has been proposed. In essence, this paper is an effort to identify and classify key aspects of MPM applications for FSI and suggest potential avenues to explore the full potential of MPM capabilities for the solution of coupled problems.

本文介绍了无网格粒子方法（MPM）在解决流体-结构相互作用（FSI）耦合问题方面的最新进展。无网格方法根据其数学公式和对计算数据点的处理进行分类。已经确定了这些方法的优点和局限性，尤其是与FSI应用有关的方法。已经提出了与FSI问题有关的显着工作的详细说明，这些问题涉及复杂的几何形状，粘性流和较大的结构变形，并且确定了基准解决方案以供将来研究。与基于网格的同类产品相比，MPM更适合于协商移动边界和复杂几何形状，这些特征是FSI问题的标志。然而，它们被更广泛接受的最大挑战是它们的实现和编程复杂性，更高的计算成本以及缺少商业软件包。到目前为止，无网格方法主要限于常规方法表现有限的应用。由于其潜在的增长潜力，分区FSI是本文的重点。针对无网格FSI问题，已对分区FSI的各个方面进行了识别和分类，包括问题制定策略，域离散化方法，求解器耦合方法，界面处理，基准问题，计算量以及商用软件的可用性。此外，还已经确定和讨论了将MPM用于FSI所涉及的各种挑战，以及在无网格方法和FSI应用中使用的最新技术，并提出了未来的发展方向。从本质上讲，本文旨在识别和分类用于FSI的MPM应用程序的关键方面，并为探索MPM功能解决耦合问题的全部潜力提供了潜在途径。
