The remainder of the EnSight documentation (as well as a version of this manual) is available online (and is accessible via the Help menu).

The other documentation is divided into three manuals:
The Ansys EnSight How-To Manual consists of relatively short articles that describe how to perform a specific operation in EnSight, such as change the color of an object or create an isosurface. Step-by-step instructions and pictures of relevant dialogs are included. In addition, each How To article typically contains numerous hyperlinks (colored blue) to other related articles (and relevant sections of the Ansys EnSight User Manual).
To access a list of the online How To articles, select Help → How to manual.... From this location, you can easily navigate to any of the articles or to the table of contents.
The Ansys EnSight User Manual provides a detailed reference for EnSight.
