A variety of particle-based methods have been developed for the purpose of computationally modelling processes that involve, for example, complex topological changes of interfaces, significant plastic deformation of materials, fluid flow in conjunction with heat transfer and phase transformation, flow in porous media, granular flow, etc. Being different from the conventional methods that directly solve related governing equations using a computational grid, the particle-based methods firstly discretize the continuous medium into discrete pseudo-particles in mathematics.The methods then mathematically solve the governing equations by considering the local interaction between neighbouring pseudo-particles. Such solutions can reflect the overall flow, deformation, heat transfer and phase transformation processes of the target materials at the mesoscale and macroscale.

In the research field of simulation-based engineering science, there are three categories of computational modelling methods, in terms of how to implement spatial discretisation. They include the Eulerian method, the Lagrangian method and the hybrid method ^{[1]}. In the Eulerian method, the computational grid does not move with the fluid flow or material deformation, while there is advection of mass between the target material and the computational grid. In the Lagrangian method, however, the computational grid moves with the flowing/deforming target material. The hybrid method uses some techniques to combine the Largangian approach with the Eulerian approach. The successful employment of an arbitrary Lagrangian–Eulerian (ALE) method in the finite element (FE) analysis software ABAQUS is a good example of the application of hybrid methods in computational modelling. The ALE adaptive meshing makes the FE computational grid “move independently of the target material”, to “maintain a high-quality mesh throughout an analysis” ^{[2]}. Regardless of what method is used to implement the spatial discretisation, the target material is assumed to be either continuous (e.g., single material/phase problems) or piecewise continuous (e.g., multi-material or multiphase problems) in the computational modelling of continuum mechanics problems. For example, in the FE modelling of solid mechanics problems, a constitutive equation, in conjunction with related boundary conditions and material properties, is solved on an FE grid, to computationally solve the boundary-value problems of solid mechanics problem. Regarding the computational fluid dynamics (CFD) modelling of single-phase incompressible Newtonian fluid flow and heat transfer problems using the finite volume method ^{[3]}, it is typical that the Navier–Stokes equations are solved on an Eulerian or Lagrangian finite volume grid. Regarding the level set method for multiphase problems, the propagation/variation of the inter-phase interface is implicitly captured by solving the level set equation on a computationally grid ^{[4]}. In the afore three examples, regardless of whether the target material is uniform (such as in the FE analysis of isotropic linear elastic materials and the CFD modelling of single-phase materials) or non-uniform (e.g., in the level set modelling of multiphase problems), the target material is always assumed to be continuous or piecewise continuous.

The benefit of treating the target material as a mathematically continuous (or piecewise continuous) medium in the computational modelling is very obvious. Firstly, it directly reflects the fundamental concept of continuum mechanics, which study the macroscopic behaviour of materials by using a continuous outlook (i.e., treating the target material as a continuous mass) ^{[5]}. Secondly, related computational modelling is normally computationally efficient. In the continuum mechanics, the particulate nature of target materials (such as material microstructure, defects, inter-atomic interactions, etc.) are not explicitly considered. The influence of such particulate nature (or properties) of the target material is normally implicitly and indirectly taken into account in the continuum mechanics by employing related macroscopic properties of the target material (such as elasticity and plasticity of solid materials, the viscosity and density of fluids, etc.) in the continuum mechanics. Related computational methods are applicable to the modelling of an appreciable volume of material (e.g., up to the volume of an entire engineering component) during a process of appreciable length (e.g., comparable to an entire engineering process).

All engineering materials consist of discrete entities (such as atoms, molecules, grains, defects, etc.). When a “discrete outlook” concept is employed, it regards the target material as a population of individual material points (or particles) that interacts with one another at very short distances ^{[5]}. Such a particulate approach studies the properties of the particulates and the interaction between the particulates. The particulates can be, as examples, atoms, molecules or any other microscopic particulates. Such an approach relates to discrete mechanics ^{[6]}. Regarding the computational modelling of materials using the concept of discrete mechanics, molecular dynamics (MD) is a good example. In MD, the target material is assumed to consist of a population of individual but interacting atoms ^{[7]}. The interaction can be mathematically formulated by using a potential function. MD implements classical mechanics to study the classical motion of many-body systems. It has been successfully employed to computationally predict, for example, the solidification of metals at the nanoscale ^{[8]}, the welding of thermosetting polymers ^{[9]}, the roll casting of Cu/Al clad plates ^{[10]} and extensive additive manufacturing ^{[11]}.

On the one hand, the modelling methods using the particulate approach can directly reflect the microscopic processes and phenomena of materials (e.g., the motion and interactions of atoms of the target material). On the other hand, such a modelling method is very computationally costly and is normally only applicable to a very small volume of material. For example, as was reviewed in ^{[12]}, there are normally a limited number of atoms in an MD simulation domain and the time window is typically on the order of magnitude of hundreds of picoseconds. It is often applied regarding the finite-size effects of such an incredibly small simulation domain (on the nanoscale) ^{[13]}. Due to such a limited length of time that can be considered in MD simulations, normally only very extreme levels of cooling rate (e.g., on the order of 10^{5} K/s ^{[13]}) can be employed in the modelling of a material during cooling.

It is clear that the modelling methods based on the “continuous outlook” concept suit applications in a large volume of material that can provide the macroscopic properties of the target material or process. The modelling methods based on the “discrete outlook” concept suit applications where the particular delicate interaction between particulates of the material is the main interest of research. In the application of computational modelling in science and engineering, there is a type of scenario where some delicate processes of a macroscopic system need to be computationally formulated and predicted. One good example of such a scenario is predicting the flow of fluid in porous media. If one only cares about the overall macroscopic properties of the flow, such as the overall static pressure loss of fluid across the porous media, one can very easily use the common Darcy’s law (or its variants) in a conventional CFD modelling based on the finite volume method ^{[14]} to get the job done. Darcy’s law assumes the porous media is a continuous uniform permeable material, i.e., a “continuous outlook”. Rather than considering the individual pores, Darcy’s law uses a loss coefficient to characterise the macroscopic properties of the porous media regarding the fluid pressure loss. However, if one cares about the pore-scale characteristics of a complex flow problem (such as multiphase flow in heterogeneous porous media) ^{[15]}^{[16]}, special care must be taken. For example, if the modelling needs to be applied to the flow problem in an appreciable volume of porous media, the “discrete outlook” that considers the actual atoms is not applicable because its computational cost is unaffordable. Some other good examples of such special scenario include high speed impact ^{[17]}, immiscible multiphase flow ^{[18]}, fluid–structure interaction ^{[19]} and flow/heat transfer involving moving boundaries ^{[20]}. All these problems in this special scenario either have complex (or moving) interfaces or involve significant and complex (as well as delicate) interface topological changes.

Lattice Boltzmann method (LBM) is a type of lattice-based pseudo-particle method. It combines the concept of material pseudo-particles (which was firstly used in the Lattice Gas Automata method) with the kinetic equations of related processes (i.e., the Boltzmann Equation) ^{[21]}. When the LBM is employed to formulate the fluid dynamics problems, it satisfies the Navier–Stokes equation on one hand, but does not explicitly solve the Navier–Stokes equation on the other hand. In the LBM, the interaction between material elements is reflected in the concept of collisions of pseudo-particles, which is mathematically formulated by using the kinetics of the probability distribution function (i.e., the Boltzmann Equation):

where 𝑓 is the probability distribution function, 𝜉 is the microscopic velocity in a direction, t is time and F is the external body force. Ω formulates the collisions between pseudo-particles, which are affected by how the material elements interact with one another as well as the material properties. For example, for fluid dynamics problem, Ω relates to the viscosity, speed of sound, temperature, density and molar mass of the target fluids.∂𝑓∂𝑡+𝜉·∇𝑓+𝐹·∇𝜉𝑓=Ω(𝑓)

By using the BGK model in conjunction with the single relaxation time approach, the discretized Boltzman equation can be formulated as ^{[22]}

𝑓𝑖(𝑥+𝑒𝑖Δ𝑡,𝑡+Δ𝑡)=𝑓𝑖(𝑥,𝑡)−1𝜏[𝑓𝑖(𝑥,𝑡)−𝑓𝑖𝑒𝑞(𝑥,𝑡)]+𝐹𝑖(𝑥,𝑡)

Ω(𝑓)=−1𝜏[𝑓𝑖(𝑥,𝑡)−𝑓𝑖𝑒𝑞(𝑥,𝑡)]

𝜌(𝑥,𝑡)=∑𝑖𝑓𝑖(𝑥,𝑡)

𝜌(𝑥,𝑡)𝑢(𝑥,𝑡)=∑𝑖𝑒𝑖(𝑥,𝑡)𝑓𝑖(𝑥,𝑡)

When the probability distribution function f only represents the likelihood of a material element having a particular velocity in a particular direction at a particular location, the corresponding LBM can be employed in the CFD modelling of fluid flow problems ^{[23]}^{[24]}. When the probability distribution functions can characterise not only velocity but also temperature (or thermal energy) of the fluid at the nodes of the computational grid, the corresponding LBM can be employed in the modelling of fluid flow in conjunction with heat transfer. For example, in the LBM modelling performed by Semma et al. ^{[25]}, a double distribution function method was used, which used one probability distribution function to formulate the flow problems and a different probability distribution function to separately formulate the heat transfer problems. If a third probability distribution function of the material solute concentration can be considered in the LBM ^{[26]}, the process of fluid flow in conjunction with heat transfer and solute transport can be simulated.

Regarding the phase transformation between the liquid and solid phases during solidification or remelting, a particular model of phase transformation is needed to formulate this, as the LBM itself is incapable. An approach similar to the enthalpy formulation of phase transformation was employed by Semma et al. ^{[25]} in the computational modelling for melting/solidification problems of pure gallium in a square cavity under the influence of natural convection, which was supported by related verification and validation. In the Enthalpy Method of phase transformation, the evolution of material enthalpy follows the below partial differential equation ^{[27]}:

∂𝐻∂𝑡+∇·(𝐶𝑝𝑇𝑢)=∇·(𝑘∇𝑇)

𝑔𝑖(𝑥+𝑒𝑖Δ𝑡,𝑡+Δ𝑡)=𝑔𝑖(𝑥,𝑡)−1𝜏[𝑔𝑖(𝑥,𝑡)−𝑔𝑖(𝑥,𝑡)𝑒𝑞]

The LBM model employing the enthalpy formulation mainly computationally formulates the process of phase transformation in the perspective of change of enthalpy of the target materials. If the specific mechanisms and mathematical formulas of solute partition in conjunction with solute diffusion/convection are well understood, the process of phase transformation (solidification or remelting) can be assumed to be driven by the difference between the local interface equilibrium composition and the local actual liquid composition of material—if the liquid phase and solid phase can be assumed to be locally in equilibrium at the interface. For example, in the modelling of the dendritic growth process during natural and forced convection ^{[26]}^{[28]}, it was assumed that the interface equilibrium composition of the liquid phase was

𝐶∗𝑙=𝐶0+{𝑇∗𝑙−𝑇𝑒𝑞𝑙+Γ𝐾[1−15𝜀𝑐𝑜𝑠4(𝜃−𝜃0)]}/𝑚

The change in solid fraction of the target material can be formulated as a function of the interface equilibrium composition of the liquid phase and the actual composition of the liquid phase:

Δ𝜙𝑠=𝐶∗𝑙−𝐶𝑙𝐶∗𝑙(1−𝑘)

Δ𝐶𝑙=Δ𝜙𝑠𝐶𝑙(1−𝑘)

ΔT=Δ𝜙𝑠𝐿𝐶𝑃

The phase field (PF) method is a diffusive interface method, which has very smooth and continuous variation across an interface between, for example, the liquid phase and the solid phase. In the LBM+CA model of phase transformation, as used in ^{[26]}^{[28]}, the process of phase transformation is solely determined by the conserved field variable—solute concentration of alloy. In the PF model of phase transformation, the phase transformation is characterised by a non-conserved field variable order parameter, which smoothly varies between 1 (solid phase) and −1 (liquid phase) regarding the phase transformation between the liquid phase and solid phase. In the LBM+PF modelling of Rátkai et al. ^{[31]} and Zhan et al. ^{[32]}, an Allen–Cahn equation governing the order parameters in conjunction with a Cahn–Hilliard equation governing the solute partition and transport was solved. The LBM+PF modelling was used to predict the sedimentation of equiaxed dendrites as well as the influence of natural convection on them in microgravity ^{[31]}, along with the influence of forced thermosolutal convection on the growth of equiaxed dendrites ^{[32]}.

The LBM method has been widely employed in the computational modelling of a variety of material processing and manufacturing processes, such as casting, welding and additive manufacturing (AM).

By using the large eddy simulation (LES) model to treat the turbulence, the LBM was employed in computational modelling to predict the fluid vortex and turbulence inside the submerged entry nozzle as well as near the mould wall of a continuous casting process ^{[33]}. The free surface flow problem of molten metal was treated as a melt–air two-phase flow problem, and the density of air was assumed to be zero. The collision-streaming approach was used to update the volume fraction of liquid for all computational cells, implementing the propagation of the melt–air interface during the melt flow during the continuous casting.

Regarding the modelling for welding, the LBM was integrated with the enthalpy method to computationally predict the remelting and, particularly, the Marangoni flow during the plasma arc welding of steels ^{[34]}. The LBM+CA method was employed to computationally predict the evolution of solidification structure during the arc welding of Inconel 601H ^{[35]}.

Regarding the application of the LBM in the computational modelling of additive manufacturing (AM) processes, Korner and co-authors have made extensive publications in this field. By using the LBM method, they computationally predicted how the evaporation process may affect the heat and mass transfer of the melt pool as well as the influence of the recoil pressure on the geometry of the melt pool during the electron beam powder bed fusion (EB-PBF) AM of a Ti alloy ^{[36]}. Practically, their LBM modelling was implemented to predict the process window of EB-PBF AM regarding, as examples, how the powder bulk density ^{[37]} or hatching process strategies ^{[38]} may affect the result of the EB-PBF AM of Ti alloys. By using the LBM+CA method ^{[39]}, the evolution of the solidification structure of IN718 during the EB-PBF AM was computationally predicted. In addition to completing some model validation, the influences of the hatching strategy on solidification structure as well as the formation of partially molten powder particles were predicted using the modelling.

By integrating the LBM with the enthalpy method ^{[40]}, Chen et al. computationally predicted (in 3D) the geometry of the consolidated Ti-6Al-4V tracks manufactured using EB-PBF AM, as well as the influence of process parameters.

While having extensive advantages, the LBM has some limitations too. For example, by employing the Chapman–Enskog analysis, the LBM can be automatically reduced to the continuity equation and momentum equation of incompressible flow problems in the limit of small Knudsen number and low Mach number ^{[41]}. If the LBM needs to be employed in the modelling of compressible flow problems at high Mach numbers, special care must be taken. In the computational modelling of immiscible multi-fluid flow using LBM, spurious currents may exist in the modelling results if the density ratio between two fluids is high. Such spurious currents may increase with the density ratio, contributing to the numerical instability of the LBM ^{[21]}. Special techniques need to be developed in order to use LBM in the modelling of multi-fluid problems that have relatively large density ratios. When trying to increase the stability of LBM models, different collision models have been developed. The physical interpretations of the collision models and why they may influence the model stability are still insufficient ^{[42]}. The LBM may also have some difficulties in the computational modelling of micro-flow problems.
