Bentley HAMMER CONNECT Edition Help

Putting It All Together

Prior to performing the calculations of transient flow and head, Bentley HAMMER CONNECT surveys the system's characteristics, considers the various pipe and fluid properties, and automatically determines an optimal time step. By default, Bentley HAMMER CONNECT uses the method of characteristics and short time steps to ensure that simulation results will be accurate enough to support firm conclusions about the effects of transients in the system. Bentley HAMMER CONNECT takes hours of guesswork about time steps and methodology out of your day, allowing you to focus on interpreting and communicating the results to stakeholders.

As a modeler, you need to focus on the following factors for a successful Bentley HAMMER CONNECT run:

  • Pick the run duration following the guidelines in Project Management and Options.
  • Enter the correct liquid properties as described in Liquid Properties.
  • Select an advanced friction model if the effects of repeated transient cycling is a concern, as described in Selecting the Friction Method.
  • Describe the boundary conditions and other hydraulic elements correctly using the information provided in Overview of Hydraulic Element Properties.

After a successful run, you need to interpret the results as described in Reviewing your Results. Perhaps you need a few runs to assess the sensitivity of your results to vapor pressure, elevations, and wave speed if the model predicts Water Column Separation and Vapor Pockets. Finally, even the most thorough analysis has little value if its conclusions and recommendations are not communicated clearly and powerfully; review the quick start lessons and the tips provided in Reviewing your Results.
