Abstract: In this article, a novel multigrid-based method is developed for modeling of electric fields and currents in electrically anisotropic and heterogeneous media. The method is useful for ...

TGMG is a software library for solving a class of elliptic partial differential equations on two-dimensional rectangular grids using the multigrid method. A defining characteristic of the library is ...

Abstract: We present a parallel multigrid method for solving variable-coefficient elliptic partial differential equations on arbitrary geometries using highly adapted meshes. Our method is designed ...

This repository contains a collection of example programs demonstrating matrix-free multigrid solvers with the deal.II finite element library. The code in this collection is based on an extension of ...

We establish the connection between the multigrid algorithms and the real-space renormalization group. This is illustrated with the example of the two-dimensional Euclidean Klein-Gordon equation with ...
