Tutorial -- Generating Initial Grids Using the LaGriT Command Language:

The steps involved in generating three dimensional grids in the LaGriT command language are:

• 1. Define mesh objects.
• 2. Define an enclosing volume.
• 3. Define interior interfaces.
• 4. Divide the enclosing volume into regions.
• 5. Assign material types to the regions.
• 6. Distribute points within the volume.
• 7. Connect the points into tetrahedra

Detailed descriptions of the LaGriT commands are given in Section II. This tutorial covers just the commands needed to generate a simple grid. The tutorial will explain how to generate a grid in a unit cube containing two materials separated by a plane. Lines that begin with an asterisk (*) are comments; keywords are in bold.
