Matrix-free implementation of the non-nested multigrid method

M Feder, L Heltai, M Kronbichler, P Munch - arXiv preprint arXiv …, 2024 - arxiv.org
Traditionally, the geometric multigrid method is used with nested levels. However, the
construction of a suitable hierarchy for very fine and unstructured grids is, in general, highly …

Efficient and scalable atmospheric dynamics simulations using non-conforming meshes

G Orlando, T Benacchio, L Bonaventura - arXiv preprint arXiv:2408.08129, 2024 - arxiv.org
We present the massively parallel performance of a $ h $-adaptive solver for atmosphere
dynamics that allows for non-conforming mesh refinement. The numerical method is based …

High-order discontinuous Galerkin methods for computational acoustics and aeroacoustics

J Heinz - 2023 - repositum.tuwien.at
Acoustic wave propagation is often simulated by solving the scalar wave equation with finite
element methods. Following this approach is known for its tendency to significant numerical …
