Welcome to the User Documentation page. Visit has several existing sources of documentation, including manuals such as: Getting Started, VisIt User's Manual, VisIt Class Slides, and Getting Data Into VisIt. This page provides links to those manuals and also includes wikis that expand on the material in the manuals.

Getting data into VisIt
VisIt can read over 100 different file formats. If you're writing data with a popular code, or using a popular format, VisIt may already have a reader for it. You can check here:
If you want to be able create simple files and get them into VisIt, here are some simple ways to do this:
- ASCII VTK Files are well supported in VisIt, and the VisItWriter library is a very lightweight way to do this.
- Existing ASCII text files, like tab- or comma-delimited data, can be pulled into VisIt: Using the PlainText reader
- Reading X/Y (curve) data
- Getting three dimensional line data into VisIt
- Reading point data
- VisItWriter
Many file formats often rely on a binary, scalable I/O layer, like HDF5 or NetCDF. However, these are usually not standalone formats themselves, but typically the basis for more comprehensive, self-describing formats. Here is some information about these I/O layers and the formats that use them:
- VisIt and HDF5
- Reading HDF5 files
- Reading HDF5 files with the XDMF reader (recommended if you do not have a dedicated VisIt database reader plugin)
- VisIt and NETCDF
- Adding a cylinder to a visualization
