Visualization Tools

We have found various other tools to be extremely useful in visualizing FLASH data outside of the fidlr routines provided in the FLASH distribution.

VisIT

Visit is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. It was developed by the Department of Energy (DOE) Advanced Simulation and Computing Initiative (ASCI) to visualize and analyze the results of terascale simulations. It is supported by Lawrence Livermore National Laboratories. Visit has a data file format specifically for reading in Flash2 and Flash3 datasets; start visit with the command line

 prompt> visit -assume_format FLASH 

Plugins for VisIT

Two plugins have been developed to assist FLASH users. Installation documentation is available in the tarballs provided below. The first plugin for Visit is available to enable compatibility with the dataset format used as of the Flash3 release. The second plugin ensures that Visit can read datasets which may have inconsistently capitalized variable names.

FlashView

FlashView is a tool for visualizing Flash datasets, which runs under Linux. Flash datasets are AMR datasets stored in the PARAMESH 3 block-structured format, and can contain several scalar variables at each point of the data domain's computational grid.
