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
