AFT Arrow 10
Significant New Features
AFT Arrow 10 incorporates over 28 new features
to make modeling gases and steam 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.
Compressor Map
Model centrifugal compressors more accurately by accounting for multiple curves from a non-dimensional or corrected Compressor Map. Use more precise flow curves obtained directly from the manufacturer.
Calculate Sound Power Levels
Estimate junction Sound Power Level according to Energy Institute Guidelines. A new output parameter has been added for Sound Power Level, as calculated by the Energy Institute Guidelines for the Avoidance of Vibration Induced Fatigue Failure in Process Pipework.
Improved Valve Window
Streamlined Design Alerts
AFT greatly simplified the Design Alert Manager to allow easier and faster specification of important design limits. The Design Alert Manager has been reorganized to improve the process of creating and applying user-defined 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
- 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
- Compressor RPM Output Parameter - Report compressor speed in RPM, in addition to percent.
- Dimensionless Heat Transfer Output Parameters - Grashof, Nusselt, Prandtl, and Rayleigh Numbers have been added as Output parameters.
- Valve xT Output Parameter - Report and graph the xT value used for valves.
- Estimated xT Output Parameter - Provide estimated xT value as used in the solver for valve loss models that do not use the Cv/xT loss model.
- Profile Graphs for Temperature Saturation and Temperature Superheat - Graph saturation temperature and temperature above saturation (superheat) along flow paths.
- Laminar Caution - Alerts the user if flow at junctions is in a laminar range.
- POR/AOR in Compressor Summary - Show the values for Preferred and Allowed Operating Ranges in the Compressor Summary.
- Events Messages in New Format - Events are now shown in a cleaner, collapsible format similar to Warnings.
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.
