New preprint published on arXiv

6 Februar 2026

Our new preprint “Smoothed aggregation algebraic multigrid for problems with heterogeneous and anisotropic materials” by Max Firmbach, Malachi Phillips, Christian Glusa, Alexander Popp, Christopher Siefert and Matthias Mayr is now available on arXiv.

This work introduces a material-aware strength-of-connection measure that enhances smoothed aggregation algebraic multigrid methods for challenging heterogeneous and anisotropic problems. By explicitly incorporating material tensor information into the coarsening process, the approach improves robustness and scalability across a wide range of academic tests and real-world applications, enabling reliable performance in large-scale high-performance computing simulations.
