Data Tutorial

This page links to materials that are used for a tutorial on getting your data into VisIt. The best source of information on making your data compatible with VisIt is the Getting Data Into VisIt Manual. The manual covers a few existing file formats and how to create data for those formats, how to create file format readers, and how to instrument simulation codes to share data in situ with VisIt.

This tutorial introduces the topics covered in the Getting Data Into VisIt Manual.
