Adaptive Mesh Refinement in Titanium

by Tong Wen, Phillip Colella - In: Proceedings of the 19th International Parallel and Distributed Processing Symposium (IPDPS , 2005
"... In this paper, we evaluate Titanium’s usability as a high-level parallel programming language through a case study, where we implement a subset of Chombo’s functionality in Titanium. Chombo is a software package applying the Adaptive Mesh Refinement methodology to numerical Partial Differential Equa ..."

COSMOLOGICAL ADAPTIVE MESH REFINEMENT

by unknown authors , 1998
"... Abstract. We describe a grid-based numerical method for 3D hydrodynamic cosmological simulations which is adaptive in space and time and combines the best features of higher order–accurate Godunov schemes for Eulerian hydrodynamics with adaptive particle–mesh methods for collisionless particles. The ..."
Abstract - Add to MetaCart
. The basis for our method is the structured adaptive mesh refinement (AMR) algorithm of Berger & Collela (1989), which we have extended to cosmological hydro + N-body simulations. The resulting multiscale hybrid method is a powerful alternative to particle-based methods in current use. The choices we

Wrinkling prediction with adaptive mesh refinement

by A. Selman, T. Meinders, A. H. Van Den Boogaard, J. Huetink - 3rd ESAFORM Conference on Material Forming , 2000
"... Abstract: An adaptive mesh refinement procedure for wrinkling prediction analyses is presented. First the critical values are determined using Hutchinson’s bifurcation functional. A wrinkling risk factor is then defined and used to determined areas of potential wrinkling risk. Finally, a mesh refine ..."

Adaptive Mesh Refinement for Storm Surge

by Kyle T. M, Clint N. Dawsona
"... An approach to utilizing adaptive mesh refinement algorithms for storm surge modeling is proposed. Currently numerical models exist that can resolve the details of coastal regions but are often too costly to be run in an ensemble forecasting framework without significant computing resources. The app ..."

Adaptive Mesh Refinement Data

by Ralf Kahler, Hans-christian Hege, Visualization Of Time-dependent
"... Analysis of phenomena that simultaneously occur on quite different spatial and temporal scales require adaptive, hierarchical schemes to reduce computational and storage demands. For data represented as grid functions, the key are adaptive, hierarchical, time-dependent grids that resolve spatio-temp ..."
