Combined Feature-Driven Richardson-Based Adaptive Mesh Refinement for Unsteady Vortical Flows
Combined Feature-Driven Richardson-Based Adaptive Mesh Unsteady Vortical Flows
2015/7/3
An adaptive mesh refinement strategy that couples feature detection with local error estimation is presented. The strategyfirst selects vortical regions for refinement using feature ...
Continuous Adjoint Approach for Adaptive Mesh Refinement
Continuous Adjoint Approach Adaptive Mesh Refi nement
2015/7/3
At present, all output-based mesh adaptation methods in the existing literature have adopted the discrete adjoint approach which, depending on the structure of the code,could be very complex to implem...

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...
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...
