 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.
