Getting Started

Tutorial Example Files:  The Cantilever Beam Problem

The example problem we will be working on for this tutorial is the cantilever beam problem.  Download this zip to get all the necessary files you need to begin working in the GUI.

GUI Launch

Upon launching the Dakota GUI for the first time, you will notice that there are five main areas on the screen:


Users of Eclipse will find this layout to be somewhat familiar.  The five main panes on the screen are as follows:

  • Project Navigator Tree (left area) – a tree view used for browsing all the components of a Dakota project.
  • Settings Editor (center area) – the main area of the screen, used for displaying the details and settings of a specific component of a Dakota project.
  • Text Editor (top-middle area) – used for viewing and editing Dakota input text files.
  • Plot View (top-right area) – used for visualizing Dakota output data as graphical plots (Note:  This view is currently disabled by default on Linux platforms due to compatibility issues)
  • Console (bottom-right area) – used for viewing console output as Dakota is running.


The Dakota GUI allows you to reorganize the layout of panes on the screen as you wish using the standard Eclipse controls for views and perspectives.  See Eclipse’s documentation on this topic if you wish to learn more.

Locate Your Dakota Executable

If you haven’t done so already, you need to let the Dakota GUI know where to find your Dakota command-line executable.  To do this, go to Window > Preferences > Dakota:


Set the path for “Dakota executable” to the command-line executable’s location on your system, then click OK.
