The particle finite element method (PFEM) in thermo‐mechanical problems [PDF]
International Journal for Numerical Methods in Engineering, 2016 SummaryThe aim of this work is to develop a numerical framework for accurately and robustly simulating the different conditions exhibited by thermo‐mechanical problems. In particular, the work will focus on the analysis of problems involving large strains, rotations, multiple contacts, large boundary surface changes, and thermal effects.The framework ...

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

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.

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

Computational analysis of contamination in Kojima Lake using upwind-type finite element method [PDF]
, 1998 We have computed the phase of spreading contaminations in Kojima Lake by using the upwind-type finite element method. We have treated the two cases: the pollutant flows from the Sasagase river and from the Kurashiki River.

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 ...
