New in Version 12

Analysis Setup

Analysis Setup window consolidates windows for System Properties, Solution Control, Activate Modules, Extended Options, Goal Seek & Control Manager, and Transient Control all into one location. This allows users to activate and enable modules, specify fluids, select a viscosity model, enable heat transfer, change solution tolerances or iterations, and so on, all from a single window. For a list of windows that have merged into the Analysis Setup window see the topic on Interface Improvements for Fathom 12.

Analysis Setup Window in AFT Fathom


The database feature interface was completely overhauled to improve workability. The new system is called the Library Manager and significantly improves the ease and workability for users to browse and connect input information, now called libraries, into their model. For a list of differences between the Database and Libraries interfaces see Interface Improvements for Fathom 12.

Multi-Scenario Graphing

Profile graphs (and Transient Graphs in the XTS module) can now include output from multiple scenarios, making it easy to compare the results along a flow path for different scenarios. See the Creating Multi-scenario Graphs tutorial.

Improved Organization of the Warnings in the Output

An improved display of the warnings and design alerts makes it easier to review and understand information in the following ways:

  • Critical Warnings, Warnings and Cautions are color-coded and grouped by type in collapsible sections

  • Design Alerts are now shown on a separate tab in the General Section

  • Double-clicking messages will take user to the related pipe/junction in the Workspace

  • Warnings, Cautions and Design Alerts are now displayed for all scenarios when using the Multi-scenario Output feature

More Improvements

  • Pipes/Junctions

    • Pipes can be defined as zero-length connectors to connect two junctions which are directly flanged together

    • Submerged pump can now be defined using surface pressure and pump depth

    • Valve transients in the XTS module can be defined as open percent vs time

  • Workspace and Interface

    • Pipes and Junctions can be set the Same as Parent directly from the Workspace

    • Custom Unit names can be defined in the Unit System section of the User Options window

    • Special Conditions can be directly changed from the toolbar for junctions that have multiple special condition options

  • Output and Reporting

    • Show the number of warnings and design alerts in the batch run window

  • Miscellaneous

    • List Junctions that have Special Conditions change in Solution Progress Window

    • Silent Batch runs can be enabled to prevent notifications from appearing over other active windows
