Agglomeration of Polygonal Grids using Graph Neural Networks with applications to Multigrid solvers

2022 · arXiv (Cornell University)

Agglomeration-based strategies are important both within adaptive refinement algorithms and to construct scalable multilevel algebraic solvers. In order to automatically perform agglomeration of polygonal grids, we propose the use of Machine Learning (ML) strategies, that …
