AFT xStream 2
Significant New Features

AFT xStream™ 2 incorporates features to make modeling and analyzing
steam and gas systems efficient so you can determine the best mitigation methods.

Analysis Setup

Updated Analysis Setup window with new areas and better user feedback of items changed or which still need to be defined

Heat Transfer

Model transient heat transfer in piping walls, including internal/external convection and thermal capacitance for more realistic simulation

Finite Tanks

Finite tank now allows specified transient heat transfer into or out of the tank, specified tank volume change over time, and more flexible initial conditions

Libraries

The Library Manager (previously the Database Manager) has been completely revised and now offers a consolidated way to use and customize libraries of fluids, pipe materials, junctions, etc.

Register for the AFT xStream 2 New Features Webinar

Watch as new features are demonstrated so you
can quickly put them into action when building
your own AFT xStream analysis models.

Other features to look forward to

Output Alerts

Warnings, errors and Design Alerts shown in the Output are now color coded and organized in a prioritized list for quick review

EOS Options

New equation of state options are available for Soave-Redlich-Kwong and Peng-Robinson

Custom Unit Names

Customize the display names for engineering units of measure to accommodate language or notation differences

Quicker Bath Runs

Run batch runs “silently” in the background to minimize interruptions as each scenario completes

Heat Transfer Parameters

Heat transfer parameters are included in the Visual Report

Workspace

  • Contextually update Junction Special Conditions directly from the toolbar

  • Reset Pipes and Junctions as ‘Same as Parent Scenario’ during specification from the Workspace Edit menu

Output

  • Design Alerts are grouped together on their own tab in the General Output section for easy identification
  • Warnings, Cautions and Design Alerts are now displayed for all scenarios when using the Multi-scenario Output feature
  • Save time with enhanced Output window data loading speed

Other

  • Batch runs of multiple scenarios now report the number of Warnings and Design Alerts in each Scenario
  • Select Special can search for text in the Pipe and Junction Notes
  • The Solution Progress window will indicate which junction had a special condition change during the run causing the model to be rerun
