Dark matter from axion strings with adaptive mesh refinement [PDF]
Nature Communications, 2022 The question of what axion mass would give rise to the observed dark matter abundance requires proper modelling of non-linear dynamics of the axion field in the early Universe.

Adaptive mesh refinement for storm surge [PDF]
Ocean Modelling, 2014 An approach to utilizing adaptive mesh refinement algorithms for storm surge modeling is proposed. Currently numerical models exist that can resolve the details of coastal regions but are often too costly to be run in an ensemble forecasting framework without significant computing resources.

Adaptive mesh refinement (AMR) criteria comparison for the DrivAer model [PDF]
HeliyonAerodynamics is one of the main areas of development in vehicle design. One of the most efficient ways of testing the aerodynamic design of a vehicle is to use Computational Fluid Dynamics (CFD), which allows for faster and more accurate aerodynamic ...

Stable Dynamical Adaptive Mesh Refinement [PDF]
Journal of Scientific Computing, 2021 AbstractWe consider accurate and stable interpolation procedures for numerical simulations utilizing time dependent adaptive meshes. The interpolation of numerical solution values between meshes is considered as a transmission problem with respect to the underlying semi-discretized equations, and a theoretical framework using inner product preserving ...

Adaptive Mesh Refinement in Titanium [PDF]
19th IEEE International Parallel and Distributed Processing Symposium, 2005 In this paper, we evaluate Titanium's usability as a high-level parallel programming language through a case study, where we implement a subset of Chombo's functionality in Titanium. Chombo is a software package applying the adaptive mesh refinement methodology to numerical partial differential equations at the production level.

Total Differential Photometric Mesh Refinement with Self-Adapted Mesh Denoising
Photonics, 2022 Variational mesh refinement is a crucial step in multiview 3D reconstruction. Existing algorithms either focus on recovering mesh details or focus on suppressing noise. Approaches with consideration of both are lacking.

Parallel Algorithms for Adaptive Mesh Refinement [PDF]
SIAM Journal on Scientific Computing, 1997 Summary: Computational methods based on the use of adaptively constructed nonuniform meshes reduce the amount of computation and storage necessary to perform many scientific calculations. The adaptive construction of such nonuniform meshes is an important part of these methods.
