What is Bentley HAMMER?
Bentley HAMMER is a powerful yet easy-to-use program that helps engineers
analyze complex pumping systems and piping networks as they transition from one
steady state to another. Hydraulic transients only last from seconds to a few minutes,
but they can damage a system or cause significant operational difficulties. For
example, Bentley HAMMER's name is due to the loud "water hammer" knocking
sound that can be heard when sudden hydraulic transients occur. Bentley HAMMER
helps engineers understand their pumping and piping networks better, enabling them
to design safe and economical surge-control systems.
Bentley HAMMER is based on technology originally created by GENIVAR (formerly
Environmental Hydraulics Group Inc.), the water Bentley HAMMER specialists, and
backed by a long-term collaboration between GENIVAR and Bentley. Bentley and
GENIVAR are committed to continuously improving Bentley HAMMER.
Capabilities of Bentley HAMMER
Bentley HAMMER's graphical interface makes it easy to quickly lay out a complex
network of pipes, tanks, pumps, and surge control equipment. You can also use
FlexTables or preset libraries to rapidly copy model parameters. If you already have a
steady-state model of your system in WaterCAD or WaterGEMS, Bentley HAMMER
can use that model file directly - saving you time and eliminating transcription errors.
You can use Bentley HAMMER to:
• Reduce the risk of transient-related damage to maximize operator safety and
reduce the frequency of service interruptions to customers.
• Reduce daily wear and tear on pumping and piping systems to maximize the
useful life of infrastructure.
• Reduce the risk of water contamination during subatmospheric transient pres-
sures, during which groundwater and pollutants could be sucked into the pipe.
27. Getting Started in Bentley HAMMER V8i
Bentley HAMMER V8i Edition User’s Guide 1-3
• Reduce the number and severity of transient forces resulting from transient pres-
sure shocks, where applicable. Transient forces and pressures can loosen joints or
grow cracks, increasing leaks and non-revenue water.
• Analyze hydropower systems complete with characteristic turbine representations
to simulate load rejection, acceptance and variation cases.
• Prepare operation checklists for use in emergencies such as power failures, pipe
breaks, and component (valve, pump) and/or control failures.
• Develop standards to ensure major water users do not damage the water system.
Information can be provided to industries to avoid sudden water takings or load
rejection. Safe speeds to open or close fire hydrants can be provided to the fire and
waterworks department.
• Provide additional information (with respect to steady-state models) to help select
pumps, locate elevated tanks, and size air valves.
Tip: Usually, hydraulic systems operate at a steady state of dynamic
equilibrium and changes in flow take minutes to hours. "Normal"
hydraulic transients may occur several times a day as pumps
start or stop. "Emergency" transients may only occur once every
month, year, or decade when power fails or pipes break.
Hydraulic transients and surge-protection needs must be
considered in the context of a water utility's risk management
and environmental protection plan.
Municipal License Administrator Auto-
Configuration
At the conclusion of the installation process, the Municipal License Administrator will
be executed, to automatically detect and set the default configuration for your product,
if possible. However, if multiple license configurations are detected on the license
server, you will need to select which one to use by default, each time the product
starts. If this is the case, you will see the following warning: “Multiple license config-
urations are available for Bentley HAMMER...” Simply press OK to clear the
Warning dialog, then press Refresh Configurations to display the list of available
configurations. Select one and press Make Default, then exit the License Adminis-
trator. (You only need to repeat this step if you decide to make a different configura-
tion the default in the future.)
Starting Bentley HAMMER V8i
After you have finished installing Bentley HAMMER, restart your system before
starting Bentley HAMMER for the first time.
28. Working with Bentley HAMMER Files
1-4 Bentley HAMMER V8i Edition User’s Guide
To start Bentley HAMMER
1. Double-click on the Bentley HAMMER icon on your desktop.
or
2. Click Start > All Programs > Bentley > Bentley HAMMER > Bentley HAMMER.
Working with Bentley HAMMER Files
Bentley HAMMER uses an assortment of data, input, and output files. It is important
to understand which are essential, which are temporary holding places for results and
which must be transmitted when sending a model to another user. In general, the
model is contained in a file with the wtg.sqlite extension. This file contains essentially
all of the information needed to run the model. This file can be zipped to dramatically
reduce its size for moving the file.
The .wtg file and the drawing file (.dwh, dgn, dwg or .sqlite) file contain user
supplied data that makes it easier to view the model and should also be zipped and
transmitted with the model when moving the model.
Other files found with the model are results files. These can be regenerated by running
the model again. In general these are binary files which can only be read by the model.
Saving these files makes it easy to look at results without the need to rerun the model.
Because they can be easily regenerated, these files can be deleted to save space on the
storage media.
When archiving a model at the end of the study, usually only the *.wtg.sqlite, *.wtg
files, and the platform specific supporting files (*.dwh, *.dgn, *.dwg or *.sqlite) need
to be saved.The file extensions are explained below:
• .bak - backup files of the model files
• .cri - results of criticality analysis
• .dgn - drawing file for MicroStation platform
• .dwg - drawing file for AutoCAD platform
• .dwh - drawing file for stand alone platform
• .sqlite - access database file for ArcGIS platform
• .nrg - results of energy calculations
• .osm - outage segmentation results
• .out - primary output file from hydraulic and water quality analyses
• .out.fl - output file from flushing analysis
29. Getting Started in Bentley HAMMER V8i
Bentley HAMMER V8i Edition User’s Guide 1-5
• .rpc - report file from hydraulic analysis with user notifications
• .seg - results of segmentation analysis
• wtg.sqlite - main model file
• .wtg - display settings (e.g. color coding, annotation)
• .xml - xml files, generally libraries, window and other settings. Some modules
like ModelBuilder also use .xml files to store settings independent of the main
model.
• .hof - results of transient analysis used by the transient results viewer
• .hmr - results of transient analysis
• .hut - transient analysis output log
• .rpt - transient analysis detailed report file
Using the Custom Results File Path Option
When the Specify Custom Results File Path option (found under Tools > Options >
Project Tab) is on for the project, the result files will be stored in the custom path spec-
ified when the project is closed. When the project is open, all of the applicable result
files (if any) will be moved (not copied) to the temporary directory to be worked on.
The result files will then be moved back to the custom directory when the project is
closed.
The advantages of this are that moving a file on disk is very quick, as opposed to
copying a file, which can be very slow. Also, if you have your project stored on a
network drive and you specify a custom results path on your local disk, then you will
avoid network transfer times as well. The disadvantages are that, should the program
crash or the project somehow doesn’t close properly, then the results files will not be
moved back and will be lost.
If you then wish to share these results files with another user of the model, you can use
the Copy Results To Project Directory command (Tools > Database Utilities > Copy
Results To Project Directory) to copy the results files to the saved location of the
model. The user receiving the files may then use the Update Results From Project
Directory command (Tools > Database Utilities > Update Results From Project Direc-
tory) to copy the results files from the project directory to their custom results file
path.
Drag-and-drop File Open
You can open model files by simply dragging them (from Windows Explorer, for
example) into the application window (stand alone version only). You can drag either
the .wtg or the .sqlite associated with the model.
