Hybrid finite difference/finite element immersed boundary method [PDF]

open access: yes, 2017
The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of ...

A multi-point constraint unfitted finite element method

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
In this work a multi-point constraint unfitted finite element method for the solution of the Poisson equation is presented. Key features of the approach are the strong enforcement of essential boundary, and interface conditions.

Dynamic Damage Quantification of Slab Tracks—Finite Element Models on Winkler Soil and Finite-Element Boundary-Element Models on Continuous Soil

open access: yesCivilEng, 2022
Train passages over intact or damaged slab tracks on different soils were calculated by two methods. The finite element method (FEM) uses a Winkler soil under the track model by adding a thin “soil layer”.

Crownwall Failure Analysis through Finite Element Method

open access: yesJournal of Marine Science and Engineering, 2020
Several failures of recurved concrete crownwalls have been observed in recent years. This work aims to get a better insight within the processes underlying the loading phase of these structures due to non-breaking wave impulsive loading conditions and to

Seepage analysis based on weak finite element method

open access: yesYantu gongcheng xuebao, 2023
In the design and operation management of hydraulic structures such as dams, gates and embankments, the seepage calculation plays a very important role. The current methods for seepage analysis are mainly based on the general finite element method. It is

Finite Element Formalism for Micromagnetism [PDF]

open access: yes, 2007
The aim of this work is to present the details of the finite element approach we developed for solving the Landau-Lifschitz-Gilbert equations in order to be able to treat problems involving complex geometries. There are several possibilities to solve the

High-Accuracy Finite Element Method: Benchmark Calculations

open access: yesEPJ Web of Conferences, 2018
We describe a new high-accuracy finite element scheme with simplex elements for solving the elliptic boundary-value problems and show its efficiency on benchmark solutions of the Helmholtz equation for the triangle membrane and hypercube.

Formulated alpha finite element method with deviatoric / volumetric split for highly precise deformation calculation by using three dimensional tetrahedral element (In case of infinitesimal isotropic elasticity)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This paper presents a novel Formulated Alpha FEM with deviatoric / volumetric split, which is combination of standard FEM and Node-based Smoothed FEM (NS-FEM), to compute highly accurate deformation in mechanical problems using tetrahedral elements.
