چکیده

Adaptive Mesh Refinement (AMR) is a highly effective method for simulations that span a large range of spatiotemporal scales, such as astrophysical simulations that must accomodate ranges from interstellar to sub-planetary. Most mainstream visualization tools still lack support for AMR as a first class data type and AMR code teams use custom built applications for AMR visualization. The Department of Energy’s (DOE’s) Science Discovery through Advanced Computing (SciDAC) Visualization and Analytics Center for Enabling Technologies (VACET) is currently working on extending VisIt, which is an open source visualization tool that accommodates AMR as a firstclass data type. These efforts will bridge the gap between generalpurpose visualization applications and highly specialized AMR visual analysis applications. Here, we give an overview of the state of the art in AMR visualization research and tools and describe how VisIt currently handles AMR data.

Parallel Rendering of 3D AMR Data on the SGI/Cray T3E

This paper describes work-in-progress on developing parallel visualization strategies for 3D Adaptive Mesh Refinement (AMR) data. AMR is a simple and powerful tool for modeling many important scientific and engineering problems. However, visualization tools for 3D AMR data are not generally available. Converting AMR data onto a uniform mesh would result in high storage requirements, and renderi...

Deploying Web-Based Visual Exploration Tools on the Grid

We discuss a web-based portal for the exploration, encapsulation, and dissemination of visualization results over the Grid. This portal integrates three components: an interface client for structured visualization exploration, a visualization web application to manage the generation and capture of the visualization results, and a centralized portal application server to access and manage grid r...

Implementing a Visualization Tool for Adaptive Mesh Refinement Data using VTK

We are currently working with several research groups who use adaptive mesh refinement, AMR, techniques for calculations in computational fluid dynamics and cosmology. The computational fluid dynamics group needed a visualization tool to visualize AMR data and to distribute with their AMR library. Since none of the widely available visualization systems directly supported visualizing AMR data, ...

Hierarchical Meshes for Volume Data

An algorithm for adaptive refinement of 3D-meshes is outlined. This algorithm is very convenient for the generation of mesh hierarchies used for efficient volume visualization algorithms, e.g. iso-surface extraction or direct volume rendering, and for multilevel finite element computations. The aim was to construct an algorithm which generates as little congruence classes as possible. The main ...
