Subdomain Deflation Combined with Local AMG: a Case Study Using AMGCL Library
Denis Demidov, Riccardo Rossi
The paper proposes a combination of the subdomain deflation method and local algebraic multigrid as a scalable distributed memory preconditioner that is able to solve large linear…
The aggregated unfitted finite element method for elliptic problems
Santiago Badia, Francesc Verdugo, Alberto F. Martín
Unfitted finite element techniques are valuable tools in different applications where the generation of body-fitted meshes is difficult. However, these techniques are prone to seve…
Robust and scalable domain decomposition solvers for unfitted finite element methods
Santiago Badia, Francesc Verdugo
Unfitted finite element methods, e.g., extended finite element techniques or the so-called finite cell method, have a great potential for large scale simulations, since they avoid…
Space-time balancing domain decomposition
Santiago Badia, Marc Olm
In this work, we propose two-level space-time domain decomposition preconditioners for parabolic problems discretized using finite elements. They are motivated as an extension to s…
