With a Geological Twist

Flash Movies can be very slow to run. If you find the download times too long, you can download all the material for the Web Display in a zip-file. From the zip-file you can then extract the movie to run on your computer instead of the server. To do this, right-click on the link to the XlFrac.exe file below and save the target to your computer. Double-click on the self-extracting exe file and save the extracted folder to a location of your choice on your computer. Inside the extracted file find a file labeled XlFrac.html. Open this file in your favorite browser to play the movie. XlFrac.exe also contains the two pdf files.

Each of the subsections under theory and analysis gives you access to three electronic documents. These documents are Portable Document Format (*.pdf) files. The documents can be read on the screen or printed. To read and print the documents, your computer will have to have Adobe's Acrobat Reader. Adobe Acrobat Reader is furnished free of charge and you can obtain it by clicking on the following button:
