Dark matter from axion strings with adaptive mesh refinement [PDF]

open access: yesNature 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 (AMR) criteria comparison for the DrivAer model [PDF]

open access: yesHeliyon
Aerodynamics 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 ...

Adaptive 3D unstructured mesh refinement [PDF]

open access: yesE3S Web of Conferences, 2020
Algorithms for generating three-dimensional detailed computational meshes are considered. The algorithms are based on adaptive refinement of the original coarse meshes describing a 3D object.

Total Differential Photometric Mesh Refinement with Self-Adapted Mesh Denoising

open access: yesPhotonics, 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.

SUHMO: an adaptive mesh refinement SUbglacial Hydrology MOdel v1.0 [PDF]

open access: yesGeoscientific Model Development, 2023
Water flowing under ice sheets and glaciers can have a strong influence on ice dynamics, particularly through pressure changes, suggesting that a comprehensive ice sheet model should include the effect of basal hydrology.

A three-dimensional robust volume-of-fluid solver based on the adaptive mesh refinement

open access: yesTheoretical and Applied Mechanics Letters, 2021
The present study provides a three-dimensional volume-of-fluid method based on the adaptive mesh refinement technique. The projection method on the adaptive mesh is introduced for solving the incompressible Navier-Stokes equations.

A Feature-Extraction-Based Adaptive Refinement Method for Solving the Reynolds Equation in Piston–Cylinder System

open access: yesLubricants, 2023
A fast local refinement algorithm based on feature extraction is developed. In the mesh-based Reynolds equation solutions, two refinement features based on the physical parameters of fluid lubrication are firstly defined, namely, pressure value feature ...

Energy calibration via correlation using an adaptive mesh refinement [PDF]

open access: yesEPJ Web of Conferences, 2020
Energy calibration via correlation has proven to be a powerful calibration method especially in the case of calibration data sets with low counting statistics. This work reports on an evolved version of this approach that uses an adaptive mesh refinement

Adaptive Grid Use in Air Quality Modeling

open access: yesAtmosphere, 2011
The predictions from air quality models are subject to many sources of uncertainty; among them, grid resolution has been viewed as one that is limited by the availability of computational resources.

Local h-adaptive refinement method applied to solid mechanics

open access: yesApplied and Computational Mechanics, 2020
A good spatial discretization is of prime interest in the accuracy of the finite element method. This paper presents a new refinement criterion dedicated to an h-type refinement method called Conforming Hierarchical Adaptive Refinement MethodS (CHARMS ...
