Least-squares hp/spectral element method for elliptic problems

The solution of elliptic boundary value problems often leads to singularities due to nonsmoothness of the domains on which the problem is posed. This paper studies the performance of the nonconforming hp/spectral element method for elliptic problems on non smooth domains. This paper deals with monotone singularities of type rα and rα log r as well as the oscillating singularities of type rα sin...

Least-squares Spectral Element Methods

In setting up this workshop we had to decide whether we wanted to let you become familiar with the method in a complex setting – non-linear, time-dependent calculations – or restrict ourselves to simpler problems, which allows you to get a better understanding of the method. We have chosen for the second line for several reasons: 1) The method is quite new, so it is hard to find references whic...

Nonconforming elements in least-squares mixed finite element methods

In this paper we analyze the finite element discretization for the first-order system least squares mixed model for the second-order elliptic problem by means of using nonconforming and conforming elements to approximate displacement and stress, respectively. Moreover, on arbitrary regular quadrilaterals, we propose new variants of both the rotated Q1 nonconforming element and the lowest-order ...

Least – Squares Method For Estimating Diffusion Coefficient

 Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...
