Finite element modelling of perturbed stellar systems [PDF]
, 2010 I formulate a general finite element method (FEM) for self-gravitating stellar systems. I split the configuration space to finite elements, and express the potential and density functions over each element in terms of their nodal values and suitable ...

Computation accuracies of boundary element method and finite element method in transient eddy current analysis [PDF]
, 1988 The computation accuracies of the boundary-element method (BEM) and finite-element method (FEM) in transient eddy-current problems are compared by using a slot-embedded conductor model and a diffusion model that can be solved theoretically. For computing

Towards computable flows and robust estimates for inf-sup stable FEM applied to the time-dependent incompressible Navier–Stokes equations [PDF]
SeMA Journal, 2017 Inf-sup stable FEM applied to time-dependent incompressible Navier–Stokes flows are considered. The focus lies on robust estimates for the kinetic and dissipation energies in a twofold sense.

Higher‐order surface FEM for incompressible Navier‐Stokes flows on manifolds [PDF]
arXiv.org, 2017 Stationary and instationary Stokes and Navier‐Stokes flows are considered on two‐dimensional manifolds, ie, on curved surfaces in three dimensions. The higher‐order surface FEM is used for the approximation of the geometry, velocities, pressure, and ...

A Review of the Application of Finite Element Method (FEM) to Localized Corrosion Modeling
Corrosion, 2019 The modeling of localized corrosion has usually focused on calculating the spatial and/or temporal distributions of chemical species, potential, and current. These are affected by the reactions considered, the geometry, and the modes of mass transport of

FEM and BEM simulations with the Gypsilab framework [PDF]
SMAI Journal of Computational Mathematics, 2018 Gypsilab is a Matlab toolbox which aims at simplifying the development of numerical methods that apply to the resolution of problems in multiphysics, in particular, those involving FEM or BEM simulations. The specifities of the toolbox, in particular its

Stable discontinuous Galerkin FEM without penalty parameters [PDF]
, 2015 We propose a modified local discontinuous Galerkin (LDG) method for second--order elliptic problems that does not require extrinsic penalization to ensure stability.

Comparison results for the Stokes equations
, 2014 This paper enfolds a medius analysis for the Stokes equations and compares different finite element methods (FEMs). A first result is a best approximation result for a P1 non-conforming FEM.

Finite element analysis of fretting crack propagation
, 2011 In this work, the finite elements method (FEM) is used to analyse the growth of fretting cracks. FEM can be favourably used to extract the stress intensity factors in mixed mode, a typical situation for cracks growing in the vicinity of a fretting ...
