AFT Fathom 13
Significant New Features
to make modeling liquid and low-velocity gases more efficient.
Workspace Layers
Customize and view model appearance, input data, and results - all in one place. Workspace Layers surpass the capabilities of the previous Visual Report feature.
4-Component Slurries
The new 4-Component Slurry model offers a comprehensive and advanced approach to slurry modeling, enabling more accurate and detailed analysis of slurry behavior in various particle size distributions
Improved Valve Window
Clarifies and expands the available valve loss models, and makes it easier to define a valve characteristic, which can be critical for an accurate model. Clearly distinguish data sources such as User Specified, Characteristic, or Handbook, to understand the available options.
Streamlined Design Alerts
Other features to look forward to
Custom Junction Icons
Isometric Freeform Drawing
New Annotations
Set Workspace Print Area
A new non-Newtonian viscosity model has been added to model power law fluids that have an apparent yield stress. (Fathom 12 and Impulse 9 only)
Customize Graph From Workspace Options
Workspace Layers:
How to use them
A group of layers is like a stack of transparencies. Each layer displays specific, customizable information and together they combine to form the Workspace view for your model. This is concept is much like Adobe Photoshop. Layers determine the visibility of the objects in the Workspace, but all objects exist regardless of visibility for connectivity and calculation purposes. Creating, customizing, and toggling Workspace Layers gives you more control over viewing your data than ever before.
Modeling Additions and Improvements
- Laminar Corrections Improvements - Laminar corrections are now off by default, messages indicate if they were applied or are recommended, and output parameters indicate the correction strength.
- Prevent Backflow at Sprays - New "No Inflow" Special Condition for Spray junctions.
- Zero-Length Connector Improvements - Zero-Length Connectors now behave like standard pipes for most features, including selection and graphing tools.
- Distinguish User and AFT Fluids - New category for user-defined fluids, making it easier to find custom entries.
New/Improved Output Parameters and Messages
- Pump RPM Output Parameter - Report pump speed in RPM, in addition to percent.
- Dimensionless Heat Transfer Output Parameters - Grashof, Nusselt, Prandtl, and Rayleigh Numbers have been added as Output parameters.
- Deep Laminar Caution - Simple loss models do not account for exceptionally laminar flow, this new message provides a caution if you enter this range.
- POR/AOR in Pump Summary - Show the values for Preferred and Allowed Operating Ranges in the Pump Summary.
- Events Messages in New Format - Events are now shown in a cleaner, collapsible format similar to Warnings.
- XTS Module Tank Overflow and Drain Warnings - New messages to clearly indicate if a Tank has overflowed or drained during the transient.
Improved Importing of PCF, EPANET, GIS, and CAESAR II models
- Import Bend r/D - Import PCF bends with appropriate r/D
- Import Speed Increase - Importing is up to 10x faster in some cases
- Better Defaults and Display for Imports - Better defaults and display options for imported models.
- Improved Import of Pipe Materials - Improved ability to link AFT pipe materials to imported pipes.
- Display CAESAR II Node Names - Display imported CAESAR II node names as junction names.
Behind the Scenes Improvements
- Graphing Optimizations - Significant improvements to backend graphing code, to provide additional stability now and more capabilities in the future.
- eLicense Access Improvements - Added heartbeat functionality to eLicense, which improves security and the release of license seats not in use.
- Output Improvements - Significant improvements to backend output code, to provide additional stability now and more capabilities in the future.
- Timed Recovery File - Automatically generate a backup of your model that can be used to recover unsaved work in the event of unexpected application closure.
