چکیده

Abstract. In this article we introduce an asymptotic preserving scheme designed to compute the solution of a two dimensional elliptic equation presenting large anisotropies. We focus on an anisotropy aligned with one direction, the dominant part of the elliptic operator being supplemented with Neumann boundary conditions. A new scheme is introduced which allows an accurate resolution of this elliptic equation for an arbitrary anisotropy ratio.

Asymptotic-preserving scheme for highly anisotropic non-linear diffusion equations

Heat transfer in magnetically confined plasmas is a process characterized by non-linear and extremely high anisotropic diffusion phenomena. Standard numerical methods, successfully employed in the numerical treatment of classical diffusion problems, are generally inefficient, or even prone to break down, when such high anisotropies come into play, leading thus to the need of new numerical techn...

Efficient Numerical Methods for Strongly Anisotropic Elliptic Equations

In this paper, we study an efficient numerical scheme for a strongly anisotropic elliptic problem which arises, for example, in the modeling of magnetized plasma dynamics. A small parameter ε induces the anisotropy of the problem and leads to severe numerical difficulties if the problem is solved with standard methods for the case 0 < ε 1 . An Asymptotic-Preserving scheme is therefore introduce...

A Hybrid Method for Anisotropic Elliptic Problems Based on the Coupling of an Asymptotic-Preserving Method with the Asymptotic Limit Model

This paper presents a hybrid numerical method to solve efficiently a class of highly anisotropic elliptic problems. The anisotropy is aligned with one coordinateaxis and its strength is described by a parameter ε ∈ (0, 1], which can largely vary in the study domain. Our hybrid model is based on asymptotic techniques and couples (spatially) an Asymptotic-Preserving model with its asymptotic Limi...

. Highly Anisotropic Temperature Balance Equation and Its Asymptotic-preserving Resolution

This paper deals with the numerical study of a nonlinear, strongly anisotropic heat equation. The use of standard schemes in this situation leads to poor results, due to the high anisotropy. An Asymptotic-Preserving method is introduced in this paper, which is second-order accurate in both, temporal and spacial variables. The discretization in time is done using an L-stable Runge-Kutta scheme. ...

An Asymptotic-Preserving all-speed scheme for the Euler and Navier-Stokes equations

We present an Asymptotic-Preserving ’all-speed’ scheme for the simulation of compressible flows valid at all Mach-numbers ranging from very small to order unity. The scheme is based on a semi-implicit discretization which treats the acoustic part implicitly and the convective and diffusive parts explicitly. This discretization, which is the key to the Asymptotic-Preserving property, provides a ...
