Efficiently Identify, Manage, and Mitigate Transient Risks
Every time a pump or valve is operated, potentially dangerous transients are introduced in your water distribution or wastewater system. Unchecked, transients can have catastrophic consequences on your pipes and equipment, operators, and customers. Quickly identify critical points in the system that need protection and facilitate sound system design.
What is OpenFlows HAMMER?
OpenFlows HAMMER helps you perform transient analysis and modeling in water or sewer systems to locate trouble spots and determine appropriate serge control strategies. OpenFlows HAMMER’s computationally rigorous engine and easy-to-use interface to efficiently identify, manage, and mitigate the risks associated with transients.

Frequently Asked Questions
A transient analysis and water hammer software, HAMMER is the most cost-effective way to control transients. Used successfully on high-profile projects around the world, HAMMER can identify critical points in the system that need protection and facilitate sound system design.
The price of OpenFlows HAMMER varies per region. While there are various types of licensing available, a common choice is the 12-month practitioner license offered through Bentley’s eStore. When you purchase through the eStore, you get a Virtuoso Subscription. This means you get the software and “Keys” (tokens) to redeem for customizable training, mentoring, and consulting services.
No. You do not need other programs to use HAMMER. HAMMER can directly read WaterCAD or WaterGEMS files, and you can import EPANET files.
HAMMER is a transient solution. WaterGEMS is a steady state solution. Even when running extended period simulation, WaterGEMS uses a series of steady state calculations.
Yes, HAMMER can work with gravity flow systems and fluids other than water.
