OpenFlows HAMMER

Water Hammer and Transient Analysis Software

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.

One-time purchase with support

Perpetual License with SELECT

A perpetual license of Bentley software is a one-time purchase, with a yearly maintenance subscription, called SELECT. This includes 24/7/365 technical support, learning resources, and the ability to exchange licenses for other software once a year. With SELECT, you will benefit from:

  • License pooling, so you can access your software from multiple computers.
  • Access additional Bentley software with Term Licenses, which allow you to pay for what you use without the upfront cost of purchasing a perpetual license.

Annual renewal quotes are delivered directly to your inbox, and our experienced Renewal Representatives are available to answer your questions and guide you through any changes you’d like to make.
