AFT xStreamReportingModelingFeatures

Reporting Features

  • Organize your design variants, operating conditions, existing infrastructure and expansions into a single file with Scenario Manager
  • Batch run operating scenarios and export your results to Excel
  • Easily compare design variant input to isolate changes between systems
  • Quickly review model input from a schematic
  • Compare transient response in different operating scenarios on a single graph
Flow Analysis Scenario Management
  • Customize and organize parameters to isolate relevant information
  • Report in multiple units, which can be updated without re-running your model
  • Filter your results to identify areas of concern
  • Export or copy results to Excel for further analysis
  • Use design alerts to quickly identify parameters outside of allowable tolerances
  • Report parameters section by section in your model
  • Save time with report-ready graphs
  • Manage graph items and templates to re-use and compare different system set-ups
  • Graph or animate parameters along a pipe length to see pressure and flow transmission
  • Graph multiple parameters over time to understand system cause-and-effect
  • Integrate flowrates to measure total flow over time
  • Visually associate parameter results with locations in the system
  • Color code your system to reflect parameter result range
  • Color animate pipes in your system to see transient behavior in context

Modeling Features

  • Select pipe materials, sizes, type and schedule from built-in or custom databases
  • Use built-in handbook data and heuristics for common component losses, embedded into pipes for visual simplicity
  • Collect and catalogue common component and pipes into custom libraries
  • Reduce redundant specification by importing your model file
  • Draw your model as an isometric or on top of an aerial photography background
  • Quickly make changes to common pipes and components with Global Edit
  • Model component losses with Cv, K, Kv, or resistance curves
  • Take control over your flow and pressure with control valves, determining valve position, capacity, and failure response
  • Utilize reactionary components like check valves, relief valves, and vacuum breaker valves to confirm your system response
  • Model relief valve protection, both internal or venting to atmosphere
  • Display effective Cv and K factor values for all valves in the system
  • Use built-in fluid databases or create your own to calculate properties
  • Mix it up with fluid mixures in NIST REFPROP or the add-on Chempak database
  • Refine your real gas modeling with equations of state (Redlich-Kwong, Three Parameter, Ideal Gas, Interpolation)
  • Account for changes in composition, density, and viscosity with pipe specific fluid properties
  • Utilize reactionary components like check valves, relief valves, and vacuum breaker valves to confirm your system response
  • Model where your system sonically chokes and determine the resulting losses
  • Induce a transient response through a valve change, pressure change, pump changes and more!
  • Use event logic to model interacting components in control systems
  • Calculate and export forces for pipe stress analysis
  • Size, locate, and test surge supression equipment like accumulators, relief valves, and vacuum breaker valves
  • Consider variable friction modeling with large flow rate changes
  • Use valve characteristic curves to capture specific valve response
  • Use pulsation analysis to determine and analyze excitable frequencies (with add-on module)
