Background of the Topic

With technological advancements in computing equipment in the last few decades, the development of effective numerical methods has become increasingly crucial for research in important subfields of modern frontier physics, such as mechanics, electromagnetics, biology, and thermodynamics. Compared with the theoretical solutions and the experimental measurements, computational models usually demonstrate satisfactory accuracy, wide applicability, and adjustable scale. By making full use of advanced computer software and hardware technologies, numerical simulations are independent of considerations about the influence of external or operation factors, such as sensor sensitivity and operator error, and can obtain detailed, rich, and intuitive physically evolving solutions. 

The most widely used methods in computational fluid dynamics are finite difference method (FDM), finite volume method (FVM), and finite element method (FEM). However, these methods usually require some special techniques in dealing with flows with free surface, multi-phase interface and moving boundaries. Special techniques to avoid mesh distortion include adaptive mesh generation and dynamic meshing technology. The computations and tracking of moving interfaces also usually require some special algorithms, such as VOF (Volume of Fluid) and LS (Level Set). In order to handle the limitations of traditional numerical methods, meshfree methods have been proposed, such as Smoothed Particle Hydrodynamics (SPH), Moving Particle Semi-implicit (MPS), and Lattice Boltzmann Method (LBM).


Goal of Topic

Meshfree methods have been widely applied into computational engineering sciences, and they are opening up new horizons of research in important fields that posed great challenges for conventional modelling capabilities previously. The main goal of this research topic is to provide a platform for researchers to exhibit the advances of theory and applications of meshfree methods in fluid mechanics and solid mechanics. With this context, the theoretical researches on meshfree methods include the improvement of accuracy, stability, and efficiency, as well as the mathematical analysis on computational aspects of meshfree techniques. The applications of meshfree methods include practical applications in engineering and sciences, as well as fluid mechanics and solid mechanics.
