Applied Flow Technology Impulse 7.0.1122 build 2020.01.30 | 324.8 mb
ATF announced the release of Impulse 7.0.1122 build 2020.01.30 is a powerful dynamic simulation and analysis tool used to calculate pressure surge transients in liquid piping systems caused by waterhammer.

Here are the top 7 features you will not want to miss out on:
- Model efficiently with layout import from file formats supported by CAESAR II®, SmartPlant®, CADWorx® and AutoCAD Plant 3D, and import / export EPANET
- Create models using an isometric grid
- Utilize color animation to visualize parameter changes over time
- Improved user interface for defining centrifugal and positive displacement pump data in the Pump Property window using automatic periodic PD pump flow calculation
- Extensive new Excel capabilities including the ability to export output using the new Excel Export Manager and even complete your exports while running batch scenarios
- Calculate buried pipe wave speed
- Ability to model Pumps as Turbines (PAT)
*** Changes for Version Date 2020.01.30 ***
>> Changes to computation logic that could impact results
- None.
>> Changes to data management that could impact results
- When using Kv (metric) loss type transient after control, the initial table entry was incorrectly selected on the basis of Cv and would start the transient at the wrong point in the transient table. This error has been resolved.
- In the Pulsation Frequency Analysis (PFA) Module, evaluating a frequency for harmonics and correlating pump speed (RPM) could cause a program lock in a specific set of circumstances. This has been fixed.
>> Changes that do not impact results
- The Excel Export Manager was not saving Settling Slurry (SSL) Module items. This has been fixed.
- The Excel Export Manager was incorrectly calculating expected rows with multi- scenario output. This has been fixed.

Waterhammer analysis tools of the past have been noted for being difficult to use and requiring extensive specialized knowledge. As a result, this critical aspect of piping system design and operation has often been overlooked. But no longer. AFT Impulse offers the ease-of-use of a drag-and-drop interface and built-in waterhammer modeling expertise. AFT Impulse helps you design and operate your systems with greater reliability and safety by avoiding the potentially catastrophic effects of waterhammer and other undesirable system transients.
Piping systems engineers typically do not have the time to become specialists in waterhammer modeling. Now they don't have to. Now they can be equipped with the proper tools to design and analyze for waterhammer transients in liquid systems containing water, petroleum and chemical products, cryogens, refrigerants and more. Waterhammer specialists will find a no compromise tool capable of modeling a broad range of waterhammer events, including transient cavitation and various surge suppression devices. AFT Impulse provides a built-in library of fluids and fittings, variable model configurations, pump and control valve modeling and much more. Scenario Manager raises the what-if potential of waterhammer modeling to a new level. Multiple system configurations varying by any modeling parameter are easily managed within a single model file with a familiar hierarchical interface. Changes in the base model are automatically inherited by alternate design cases.
AFT Impulse incorporates a steady-state solver providing seamless transfer of initial conditions to the transient analysis. The traditional Method of Characteristics are employed to solve the transient mass and momentum equations of pipe flow. Modeling vapor cavitation and liquid column separation, the effect of pressure surges due to vapor cavity collapse may be evaluated. Modeling tools for a wide range of system components and surge devices are included. Transients can be initiated based on time or on events in the system. For example, a valve closure transient may be initiated when a specified pressure level is attained at a location. From the powerful drag-and-drop model building features to the fully customizable output, AFT Impulse is a powerful tool ready to tackle your most demanding design problems.
