The following tutorial illustrates some of the basic concepts and uses of the command line interface to MeshTV.
Before starting on the tutorial, you will need the following:
· A SILO file, preferrably "rect2d.silo" which can typically be retrieved at
/usr/local/meshtv/data/rect2d.silo
· Access to the executable meshtvx . If when you type meshtvx you get the message:
then meshtvx is either not on your machine or not in your search path. Contact your system administrator for assistance.
For the purpose of this tutorial, the following typographical conventions will be used:

1. Begin the command line interface to MeshTV.
open /usr/local/meshtv/data/rect2d.silo
3. List the contents of the file (shows the names of all variables and meshes.)
6. Make a contour plot of density.
8. Change the contour levels by percent.
9. Generate a pseudo-color contour plot of pressure.
10. Find the min and max values of pressure.
11. Set the range for the pseudo-color plot.
12. Use the pick and query facility. Use left mouse button to select points.
13. Plot a mesh in another color on top of current plot.
14. Change the window limits (using physical/problem dimensions).
15. Reset the physical window limits.
16. Change to four output windows.
18. Generate a material-boundary plot.
19. Change the active window and generate a solid-material plot.
20. Generate a distance plot of density. Use the left mouse button to select the two endpoints of a line (within window 3).
