An ellipsoidal particle–finite element method for hypervelocity impact simulation [PDF]
International Journal for Numerical Methods in Engineering, 2003 AbstractA number of coupled particle–element and hybrid particle–element methods have been developed for the simulation of hypervelocity impact problems to avoid certain disadvantages associated with the use of pure continuum‐based or pure particle‐based methods. To date these methods have employed spherical particles.

Quasi-3-D spectral wavelet method for a thermal quench simulation
Journal of Mathematics in Industry, 2021 The finite element method is widely used in simulations of various fields. However, when considering domains whose extent differs strongly in different spatial directions a finite element simulation becomes computationally very expensive due to the large

Hybrid finite element and Brownian dynamics method for charged particles [PDF]
The Journal of Chemical Physics, 2016 Diffusion is often the rate-determining step in many biological processes. Currently, the two main computational methods for studying diffusion are stochastic methods, such as Brownian dynamics, and continuum methods, such as the finite element method. A previous study introduced a new hybrid diffusion method that couples the strengths of each of these

Electromagnetic PIC simulations with smooth particles: a numerical study*
ESAIM: Proceedings and Surveys, 2016 In this article we study a charge-conserving finite-element particle scheme for the Maxwell-Vlasov system that is based on a div-conforming representation of the electric field and we propose a high-order deposition algorithm for ...

A Smooth Partition of Unity Finite Element Method for Vortex Particle Regularization [PDF]
SIAM Journal on Scientific Computing, 2017 We present a new class of $C^\infty$-smooth finite element spaces on Cartesian grids, based on a partition of unity approach. We use these spaces to construct smooth approximations of particle fields, i.e., finite sums of weighted Dirac deltas. In order to use the spaces on general domains, we propose a fictitious domain formulation, together with a ...

Seakeeping with the semi-Lagrangian particle finite element method [PDF]
Computational Particle Mechanics, 2017 The application of the semi-Lagrangian Particle Finite Element Method (SL–PFEM) for the seakeeping sim-ulation of the Wave Adaptive Modular Vehicle under spray generating conditions is presented. The time integration of the Lagrangian advection is done using the explicit integra-tion of the velocity and acceleration along the streamlines (X-IVAS ...
