Feature-Driven Cartesian Adaptive Mesh Refinement in the Helios Code
Feature-Driven Cartesian Adaptive Mesh Refinement Helios Code
2015/7/3
Feature-detection methods are applied to drive Cartesian-based adaptive mesh re nement for improved vortex resolution in aerodynamics ow elds. Several approaches such as the Q-criterion, the eigenvalu...
Mesh refinement and modelling errors in flow simulation
Mesh refinement modelling errors flow simulation
2015/7/1
We present a perspective on verification and validation of CFD tools for analysis and design, identifying principal sources of error due to approximations in the physical model, numerical discretizati...
Extension of the Finite Integration Technique including dynamic mesh refinement and its application to self-consistent beam dynamics simulations
Finite Integration Technique, Adaptive Dynamic Mesh Refinement, Particle-In-Cell
2011/9/6
An extension of the framework of the Finite Integration Technique (FIT) including dynamic and adaptive mesh refinement is presented. After recalling the standard formulation of the FIT, the proposed m...
Radiative cooling in numerical astrophysics: the need for adaptive mesh refinement
Computational techniques fluid dynamics Radiative recombination Radiative transfer in astrophysics
2010/11/15
Energy loss through optically thin radiative cooling plays an important part in the evolution of astrophysical gas dynamics and should therefore be considered a necessary element in any numerical simu...
Dynamic Adaptive Mesh Refinement for Topology Optimization
Dynamic Adaptive Mesh Refinement Topology Optimization
2010/12/13
We present an improved method for topology optimization with both adaptive mesh refinement and
derefinement. Since the total volume fraction in topology optimization is usually modest, after a few in...

The paper presents an adaptive parametric study on mesh refinement during adaptive finite element analysis of sheet forming operations. The selected adaptivity parameters for the study are field varia...
An Edge-based Anisotropic Mesh Refinement Algorithm and its Application to Interface Problems
Adaptive finite element method Anisotropic mesh refinement El- liptic interface problem Non-homogeneous jump A posteriori error estimate
2015/5/6
Based on an error estimate in terms of element edge vectors on arbitrary unstruc-tured simplex meshes, we propose a new edge-based anisotropic mesh refinement algorithm. As the mesh adaptation indicat...
