Walk-Through Examples
(Metric Units)
The AFT Fathom Walk-Through Examples are designed to get new users trained to use AFT Fathom correctly in the shortest amount of time. If you are using AFT Fathom for the first time, start with the Beginner - Three Reservoir Example because it offers an in-depth explanation of how to use AFT Fathom. Otherwise, choose an example from the table below that you wish to learn more about. For examples using the AFT Fathom Add-on Modules, see the AFT Fathom Modules Overview.
Completed versions of the example model files are included with the default installation: C:\AFT Products\AFT Fathom 13\Examples
Note: The examples are available in both English and Metric units. To work these examples in a different unit system, open the appropriate example, and click the link to the alternate unit system found at the top of each example.
