The Immersed Interface Method for Elliptic and Parabolic Problems with Discontinuous Coefficients

  title={The Immersed Interface Method for Elliptic and Parabolic Problems with Discontinuous Coefficients},
  author={Noufe H. Aljahdaly},
In this paper we consider numerical methods for solving elliptic as well as time dependent advection- diffusion-reaction (ADR) equations in one spatial dimension. We consider the case in which the difference diffusion coefficients as well as advection coefficients and reaction coefficients are discontinuous across a fixed interface. Using the immersed interface method (IIM) for finite difference approximations, we demonstrate how to modify numerical methods constructed for the constant…

A Modified Algorithm Based on Haar Wavelets for the Numerical Simulation of Interface Models

In this paper, a new numerical technique is proposed for the simulations of advection-diffusion-reaction type elliptic and parabolic interface models. The proposed technique comprises of the Haar

Application of Rbf-Fd to Wave and Heat Transport Problems in Domains with Interfaces

This work considers the 2D forward modeling problem, and develops spatial discretization based on radial-basis-functiongenerated finite differences based on piecewise polynomials to provide third-order accuracy not only throughout smooth regions, but also for wave reflections and transmissions at arbitrarily curved material interfaces.



Simplified immersed interface methods for elliptic interface problems with straight interfaces

This article proposes simplified immersed interface methods for elliptic partial/ordinary differential equations with discontinuous coefficients across interfaces that are few isolated points in 1D, and straight lines in 2D using a conservative second‐order finite difference scheme whose coefficient matrix is symmetric and definite.

Finite difference methods for ordinary and partial differential equations - steady-state and time-dependent problems

This book discusses infinite difference approximations, Iterative methods for sparse linear systems, and zero-stability and convergence for initial value problems for ordinary differential equations.
