Adaptive Grid Use in Air Quality Modeling
Atmosphere, 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.

Adaptive Finite Volume Method for the Shallow Water Equations on Triangular Grids
Advances in Mathematical Physics, 2016 This paper presents a numerical entropy production (NEP) scheme for two-dimensional shallow water equations on unstructured triangular grids. We implement NEP as the error indicator for adaptive mesh refinement or coarsening in solving the shallow water ...

Mesh adaptation in 3D numerical modeling of heat conductivity [PDF]
Computer Methods in Materials Science, 2009 Numerical modeling of heat conductivity in 3D is complex and time consuming issue. Mesh adaptation is one of the methods which shortens calculations time in comparison to solution on dense mesh and gives exact results, in comparison to coarsen mesh ...

Improvements of efficiency of finite element simulations of solidification due to adaptive mesh refinement and time-step selection [PDF]
Computer Methods in Materials Science, 2004 The paper deals with an application of adaptive mesh refinement and automatic time-step selection techniques to numerical simulations of solidification. High cooling and heating rates in the beginning of the process involve the need for using very small ...

Issues in adaptive mesh refinement [PDF]
2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW), 2010 In this paper, we present an approach for a patch-based adaptive mesh refinement (AMR) for multi-physics simulations. The approach consists of clustering, symmetry preserving, mesh continuity, flux correction, communications, management of patches, and dynamical load balance.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...
