Generalizations of the Finite Element Method
Open Mathematics, 2011 Abstract This paper is concerned with the generalization of the finite element method via the use of non-polynomial enrichment functions. Several methods employ this general approach, e.g. the extended finite element method and the generalized finite element method.

Analysis of Chisel Plough Shovel Designs Using Finite Element Methods
Iraqi Journal of Industrial ResearchThe chisel plow is the most common plow due to its ease of operation. It goes deep into the soil to a relatively large depth. It also does not leave large clumps on the soil surface after plowing, as it breaks and loosens the soil without turning it. In

FLOW SIMULATIONS IN CROSS-FLOW FANS USING THE FINITE ELEMENT AND FINITE VOLUME METHODS
TASK Quarterly, 2004 Both basic computational fluid dynamics methods: the finite element method (FEM) and the finite volume method (FVM) have been used to simulate flow fields in a cross-flow fan (CFF).

Deep Ritz - Finite element methods: Neural network methods trained with finite elements
Computer Methods in Applied Mechanics and EngineeringWhile much attention of neural network methods is devoted to high-dimensional PDE problems, in this work we consider methods designed to work for elliptic problems on domains $Ω\subset \mathbb{R} ^d, $ $d=1,2,3$ in association with more standard finite elements. We suggest to connect finite elements and neural network approximations through training, i.

Error inhibiting methods for finite elements
ESAIM: Mathematical Modelling and Numerical AnalysisFinite Difference methods (FD) are one of the oldest and simplest methods for solving partial differential equations (PDE). Block Finite Difference methods (BFD) are FD methods in which the domain is divided into blocks, or cells, containing two or more grid points, with a different scheme used for each grid point, unlike the standard FD method. It was

A Comparative Finite Element Analysis of Two Surgical Methods for Cryptotia
Plastic and Reconstructive Surgery, Global Open, 2019 Background:. Cryptotia is an auricular muscle abnormality that causes the superior and posterior auricular area to be buried under the temporal skin. Surgical treatment approaches can be divided into skin grafts and local flaps.

Multigrid for the Mortar Finite Element Method
SIAM Journal on Numerical Analysis, 2000 The authors deal with a multigrid technique for uniformly preconditioning linear systems arising from a mortar finite element discretization of second order elliptic boundary value problems. Although the results reported in the paper are stated for a model problem (Poisson equation with Dirichlet and Neumann boundary conditions on the different parts ...
