New in Version 11
Scenario Comparison Tool
-
Quickly get a comparison of different scenarios within a model file
-
Useful to double-check input results for old models, or for troubleshooting purposes
-
For a detailed description, see Scenario Comparison Tool Overview
Multi-scenario Pump vs. System Curves
-
Pump vs System curves from different scenarios can be plotted on the same graph within AFT Fathom
-
Easily compare changes to pump operation in different cases
-
For more information see Multi-Scenario Pump vs. System Curves Tutorial
Junction- specific Parameters in Visual Report
-
Output such as the percent of BEP for a pump or the Cv of a control valve can now be displayed in the Visual Report
Notes in Output
-
Notes can be added to any cells in the Output to save observations and comments directly with the model file
New Workspace Functionality
-
Multi-level Undo - Drawing, arranging and moving objects in the Workspace now allows for multiple levels of undo
-
Workspace Magnifier - The magnifier tool provides an enlarged view of sections of the model to make it easier to manage and navigate large models
-
Automatic Junction Rotation - Fathom will automatically rotate junctions to visually align with neighboring pipes to speed-up model formatting
-
Combine Pipes - a series of pipes and junctions can be combined to simplify a model, with any losses being imported to the Pipe Fittings and Losses tab, and any elevations being imported as Intermediate Pipe Elevations
-
Split Pipes by Intermediate Elevations - Pipes with intermediate elevations can be split with branches at intermediate elevation points (see Joining and Splitting Pipes)
-
Select Shortest Flow Path - The shortest path between two selected junctions can be found using this feature in the Edit menu
Diagnostics Window
-
Provides a list of features and settings which might cause issues as a starting point for model troubleshooting
-
See the Diagnostics Window topic for more information
More Improvements
-
Overall Performance
-
Improved intelligence on when a model needs to be saved and re-run to preserve the output
-
Faster model loading speed
-
Improved language refresh speed
-
New and updated themes
-
Workspace
-
The Undefined Objects panel remains open when pipes/junctions are being edited
-
Double-clicking a junction allows more than one of that junction to be placed in the Workspace at a time
-
Snapping can be turned off for pipes when the isometric drawing mode is enabled
-
Output
-
Output parameters can now be filtered/searched for simpler selection
-
The average thermal conductivity used for calculations can be displayed in the Output
-
Visual Report
-
Visual Report Control has been redesigned to better filter parameters
-
Pipes
-
Heat tracing now allows the entry of power/length and number of turns to allow Fathom to calculate the heat flux directly
-
Junctions
-
Updated Tee/Wye Properties window which clarifies the input and automatically defines the pipe arrangement according to the direction and orientation on the Workspace
-
Built-in K values are now included for bends with r/D between 0.5 and 1
-
Notes can be globally edited for junctions
-
Design Alerts
-
Design Alerts can be saved to and loaded from a file to quickly apply common Design Alerts to multiple models
-
Ability to import custom Fittings & Losses from a file
