Optimization Of Curved Plated Structures With The Finite Strip And Finite Element Methods

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2015
The aim of this study is to compare two available numerical tools for solving of partial differential equations for the optimal design of structures. In the past years numerous methods were developed for topology optimization, from these we have adopted ...

Finite element least-squares methods for a compressible stokes system

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
The least-squares functional related to a vorticity variable or a velocity flux variable is considered for two-dimensional compressible Stokes equations. We show ellipticity and continuity in an appropriate product norm for each functional.

Accurate gradient computations at interfaces using finite element methods

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
New finite element methods are proposed for elliptic interface problems in one and two dimensions. The main motivation is to get not only an accurate solution, but also an accurate first order derivative at the interface (from each side).

Automating the Finite Element Method [PDF]

open access: yesArchives of Computational Methods in Engineering, 2007
The finite element method can be viewed as a machine that automates the discretization of differential equations, taking as input a variational problem, a finite element and a mesh, and producing as output a system of discrete equations. However, the generality of the framework provided by the finite element method is seldom reflected in ...

Thermal energy storage in combined cycle power plants: comparing finite volume to finite element methods [PDF]

open access: yesE3S Web of Conferences, 2019
The research in thermal energy storage (TES) systems has a long track record. However, there are several technical challenges that need to be overcome, to become omnipresent and reach their full potential. These include performance, physical size, weight

Combining the DPG Method with Finite Elements [PDF]

open access: yesComputational Methods in Applied Mathematics, 2017
Abstract We propose and analyze a discretization scheme that combines the discontinuous Petrov–Galerkin and finite element methods. The underlying model problem is of general diffusion-advection-reaction type on bounded domains, with decomposition into two sub-domains.
