36. VisIt

The developers of FLASH also highly recommend VisIt, a free parallel interactive visualization package provided by Lawrence Livermore National Laboratory (see https://wci.llnl.gov/codes/visit/). VisIt runs on Unix and PC platforms, and can handle small desktop-size datasets as well as very large parallel datasets in the terascale range. VisIt provides a native reader to import FLASH2.5 and FLASH3. Version 1.10 and higher natively support FLASH3. For VisIt versions 1.8 or less, FLASH3 support can be obtained by installing a tarball patch available at http://flash.rochester.edu/site/flashcode/user_support/visit/. Full instructions are also available at that site.
