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.

Parallel Algorithms for Adaptive Mesh Refinement [PDF]

open access: yesSIAM 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.

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.

Reinforcement Learning for Adaptive Mesh Refinement

open access: yesCoRR, 2021
Large-scale finite element simulations of complex physical systems governed by partial differential equations (PDE) crucially depend on adaptive mesh refinement (AMR) to allocate computational budget to regions where higher resolution is required. Existing scalable AMR methods make heuristic refinement decisions based on instantaneous error estimation ...

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

Metrics for Performance Quantification of Adaptive Mesh Refinement [PDF]

open access: yesJournal of Scientific Computing, 2021
AbstractNon-uniform, dynamically adaptive meshes are a useful tool for reducing computational complexities for geophysical simulations that exhibit strongly localised features such as is the case for tsunami, hurricane or typhoon prediction. Using the example of a shallow water solver, this study explores a set of metrics as a tool to distinguish the ...
