Modeling software
Heads up! This is an initial draft created with a bit of AI/LLM assistance — I'll be rewriting these sections soon. Check the changelog for updates on what's done.
Introduction
Modeling software for hydraulic systems falls into two main categories: desktop and web-based applications. Desktop software is often used for detailed, long-term planning due to its comprehensive features. On the other hand, web-based models are designed for operational tasks, with a focus on real-time data integration.
This section will explore the key features of each type and how their pricing models have evolved to meet different engineering and operational needs.
Software types
Desktop applications
Historically, desktop applications have focused on long-term planning and have primarily been used by engineers. These tools are feature-rich, mature, and typically require an experienced operator to manage their complexities effectively.
Desktop applications have traditionally followed an enterprise pricing model that includes perpetual licensing with an annual maintenance fee. In this model, a user pays a significant upfront fee to own the software at its current version and then pays an annual fee for ongoing support. This support includes software updates as well as assistance with usage or technical issues from the software vendor.
However, the pricing strategy for desktop software is evolving, with many vendors now adopting a Software as a Service (SaaS) model. In this model, users pay a recurring fee for a set number of licenses, aligning more with modern business practices and trends.
Web-based applications
In recent years, both existing vendors and new companies have expanded into the web-based application space. This shift has also seen the broader use of hydraulic models beyond traditional planning and the exclusive use by engineers and hydraulic modelers.
Web-based applications are increasingly focused on operational uses, daily management tasks, and analytical and reporting capabilities. These platforms often integrate more seamlessly with live data, facilitating the creation of digital twins—dynamic, real-time replicas of physical systems.
These dynamic, real-time replicas of physical systems help utilities manage and monitor their networks with precision, respond quickly to changing conditions, and improve operational efficiency.
Additionally, web-based applications make sophisticated hydraulic modeling tools available to more people within an organization, supporting more collaborative and data-driven decision-making in water management.
Hydraulic engines
As mentioned in the "What are water models?" section, EPANET has become the industry standard for modeling engines since its release by the U.S. Environmental Protection Agency (EPA). Its public domain status allowed commercial vendors to build advanced graphical user interfaces (GUIs) on this dependable engine, making it a core component of many current hydraulic modeling tools.
However, there are exceptions where some platforms have developed and maintained their own proprietary engines, often built around the same time or even before EPANET was introduced. For instance, both InfoWorks WS Pro and KYPipe continue to use custom hydraulic engines. These platforms have opted to enhance and expand their original technology rather than adopting EPANET’s engine, providing specialized functionalities that cater to specific modeling needs.
Overview of available software
The following section will explore common applications for hydraulic modeling, comparing desktop and web-based platforms. It will cover the specific features of each software, how they serve different engineering requirements, and the practical aspects of their use. You will also find information on training resources and community support available to enhance your skills in these tools.
Moreover, we will examine the pricing structures to provide a clear understanding of the costs involved. This guide aims to help you understand the options available to you, enhancing your ability to make informed decisions about the software that aligns with your operational and strategic needs
