Isogeometric multi-patch preconditioner for time-dependent electromagnetic problems

Bernard Kapidani, Gabriele Loli, Giancarlo Sangalli +2

We build upon recent developments in high-order spline-based geometric methods for the three-dimensional initial boundary value problem of Maxwell's equations. Previous schemes wer…

The Isogeometric Fast Fourier-based Diagonalization method

Monica Montardini, Stefan Takacs, Mattia Tani

The construction of robust solvers for linear systems obtained from the discretization of partial differential equations using Isogeometric Analysis is challenging since the condit…

Factorizations and fast diagonalization for the heat equation

Andrea Bressan, Alen Kushova, Gabriele Loli +3

This work investigates diagonalization-based methods for efficiently solving linear evolution problems, with a particular focus on the heat equation. The plain diagonalization of t…

A low-rank solver for conforming multipatch Isogeometric Analysis

Monica Montardini, Giancarlo Sangalli, Mattia Tani

In this paper, we propose an innovative isogeometric low-rank solver for the linear elasticity model problem, specifically designed to allow multipatch domains. Our approach splits…

Space-time least squares approximation for Schrödinger equation and efficient solver

Andrea Bressan, Alen Kushova, Giancarlo Sangalli +1

In this work we present a space-time least squares isogeometric discretization of the Schrödinger equation and propose a preconditioner for the arising linear system in the paramet…

A low-rank isogeometric solver based on Tucker tensors

Monica Montardini, Giancarlo Sangalli, Mattia Tani

We propose an isogeometric solver for Poisson problems that combines i)low-rank tensor techniques to approximate the unknown solution and the system matrix, as a sum of a few terms…
