FLASH-AVM

A matlab-based analysis and visualization toolkit for the FLASH simulation code.

FLASH Analysis and Visualization with Matlab. A Matlab-based analysis and visualization toolkit for the FLASH simulation code (http://flash.uchicago.edu/site/flashcode/). While many visualization software are compatible with FLASH data, few are well-suited for making publication-quality figures. The intent of FLASH-AVM is to provide a Matlab-based alternative to the yt python package (https://yt-project.org/docs/dev/index.html), capable of producing high quality visualizations of volumetric data. The toolkit allows the user to read from and write to multi-dimensional, multi-block, adaptive mesh refinement (AMR) FLASH HDF5-formatted checkpoint or plot files, and to design their own custom analysis and visualization scripts. Reader files allow the user to read in AMR data and plot or post-process the data. Capabilities include: prolonging coarse data to the finest available level, plotting mesh block outlines. Currently the code is limited to two-dimensional datasets, but the capability to handle three-dimensional datasets is coming soon. One example is provided of the two-dimensional Sedov problem with multiple levels of adaptive mesh refinement active. The code is currently in its infancy, and collaboration with interested parties is welcome.
