Particle in Cell Finite Element Validation and Verification Methods
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020Particle in cell codes are used extensively to understand plasma physics and to design devices that exploit these physics. More recent needs (say novel table top accelerators) have given impetus to development of the next generation plasma physics codes that have better fidelity. But despite this need, it is difficult to validate any code.

Bridging Scale Particle and Finite Element Methods
2006We summarize the strengths and limitations of currently available multiple-scale techniques, where the emphasis is made on the latest prospective approaches, such as the bridging scale method, multiscale boundary conditions, and multiscale fluidics. Example problems, in which multiple-scale simulation methods yield equivalent results to full atomistic ...

Moving particle finite element method with global smoothness
International Journal for Numerical Methods in Engineering, 2004AbstractWe describe a new version of the moving particle finite element method (MPFEM) that provides solutions within a C0 finite element framework. The finite elements determine the weighting for the moving partition of unity. A concept of ‘General Shape Function’ is proposed which extends regular finite element shape functions to a larger domain ...

A hybrid particle-finite element method for impact dynamics
Nuclear Engineering and Design, 2011Abstract An attachment algorithm for the coupling of smoothed particle hydrodynamics (SPH) and finite element method (FEM) is proposed to take advantage of the best properties of both methods. In the SPH-FEM attachment algorithm, SPH particles are attached to finite element nodes in the coupling interface. Any FE node that is in the support domain of

Dynamic simulation of drops by the particle finite element method
2021Liquid drop dynamics on solid surfaces play an important role both in nature and engineered applications. The prediction of drop spreading and/or sliding motions has far-reaching implications in many fields of application, including microfluidics, phase change applications, or coating technology.

Coupling of smooth particle hydrodynamics with the finite element method
Nuclear Engineering and Design, 1994Abstract A gridless technique called smooth particle hydrodynamics (SPH) has been coupled with the transient dynamics finite element code pronto . In this paper, a new weighted residual derivation for the SPH method will be presented, and the methods used to embed SPH within pronto will be outlined.

A study of compaction of composite particles by multi-particle finite element method
Composites Science and Technology, 2009We study the compaction of composite mixture of soft and hard micro-/nano-size particles using multi-particle finite element method. In this method, each particle is fully discretized into finite element mesh. Local non-uniform contact deformation and non-uniformity stress chains transmitted through the composite are well illustrated.

Finite element-particle method calculation of EHD plumes
Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2003We use the superparticle technique mixed with finite element methods to study the transient and stationary behavior of EHD flows. Calculations show that the technique is suitable to study EHD flows. We have been able to reproduce fairly well the particle distribution and flow pattern for both transient and steady EHD plumes.

On the Treatment of Plastic Deformation in the Particle Finite Element Method
PAMM, 2018AbstractThe particle finite element method (PFEM) combines the benefits of discrete modeling techniques and approaches based on continuum mechanics. It provides a convenient tool to deal with the problem of large configurational change, such as metal cutting, in which nonlinear plasticity plays a key role [1].

Particle Finite Element Methods in Solid Mechanics Problems
2007The paper examines the possibilities of extending the Particle finite element methods (PFEM), which have been successfully applied in fluid mechanics, to solid mechanics problems. After a review of the fundamentals of the method, their specific features in solid mechanics are presented.
