AFT xStream 3.0.1113 (Win)

AFT xStream 3.0.1113 is a cutting-edge simulation tool for engineers and system designers working with steam and gas piping networks. It specializes in modeling high-speed, acoustic transients, enabling accurate prediction of pressure surges, flows, and system responses during turbine trips, compressor shutdowns, and other dynamic events. By simulating these transients, AFT xStream helps reduce operational uncertainties, optimize design, and save time and costs.

The software allows comprehensive modeling of steam and gas systems, including tank blowdowns, charging operations, heat exchanger tube ruptures, and choked flow conditions. Users can adjust transient input data, such as valve positions, pressures, temperatures, and control set points, to accurately simulate real-world scenarios. Transients can be initiated based on defined time intervals or triggered by specific system events.

AFT xStream integrates a steady-state solver to automatically initialize the system before transient analysis and uses automatic pipe sectioning to enhance simulation accuracy. Compound transient event logic allows complex control sequences to be modeled effectively, while the scenario manager enables tracking of multiple design variants in a single model file. Integrated graphing, reporting, and animation tools provide visual insight into complex system behavior.

The software is fully compatible with major pipe stress dynamic models like CAESAR II®, ROHR2, AutoPIPE, and TRIFLEX®. Built-in libraries include fluids, fittings, NIST REFPROP, and ASME Steam Tables, with the Chempak™ add-on providing a database of nearly 600 gases for advanced flow mixing simulations. The user interface supports both 2D flow diagrams and isometric views for a flexible and intuitive experience.
