What data file formats can VisIt read?
VisIt can read several dozen file formats. The table below lists some of the most popular data file formats that VisIt can currently read in and visualize. For a complete list of supported file formats, at the time of the last documentation revision, look in the VisIt User’s Manual. You can also look at the What’s New page for more supported file formats. Finally, the File formats table at visitusers.org is another good resource. Each file format is read in by a database reader plug-in that is distributed with VisIt. If you want to use VisIt with your data, you can write your data to a file format that VisIt already understands or you can write your own database reader plug-in. You can find out more about writing compatible files and writing a database reader plug-in in the Getting Data Into VisIt manual.
