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.
