Flow Science, Inc. reports the FLOW-3D HYDRO Symposium 2025, taking place October 13-15, 2025, at the historic Brown Palace Hotel in Denver, CO. The symposium will bring the greater water engineering community and the FLOW-3D HYDRO user community together for a collaborative exploration of computational fluid dynamics across the water industry.
“This will be the first FLOW-3D HYDRO Symposium—actually, the first industry-focused event that Flow Science has organized, so that’s very exciting” says Flow Science President, John Wendelbo. “Modelers in water engineering are a passionate, connected community and we’re looking forward to a lot of engagement. This input from the community of practice is what drives us to keep pushing the envelope and providing the best CFD modeling solutions for the industry.”
Themes of the symposium include the value of best practices in producing well understood, defensible CFD results, effective communication of CFD results, the benefits of automation-driven modeling approaches, and fostering connections between future engineering graduates and engineering professionals.
The 3-day event will begin with an evening reception and academic poster session. The poster session offers students opportunity to share their engineering research and modeling experience with an audience of professionals and fellow CFD enthusiasts in academia, while giving current professionals a chance to connect with the next generation of water engineers. An award for best poster will be announced at the symposium dinner on October 14.
The symposium will feature invited speakers from Mott MacDonald, Stantec, Verdantas and Colorado State University. Topics include FLOW-3D HYDRO for river mechanics, wastewater treatment plant applications, communication of simulation results to stakeholders, and using CFD as a teaching tool in university engineering programs.
There will also be technical presentations from Flow Science engineers on topics such as air entrainment modeling, using automation tools to achieve greater simulation efficiency and accuracy, and best CFD modeling practices. Participants will get to test and expand their simulation skills through an interactive CFD modeling challenge and a hands-on FLOW-3D (x) workshop.
“Our goal is to help strengthen and build interest and awareness of what CFD can do, not just among our customers, but throughout the broader water engineering community,” says Flow Science Global Water Infrastructure Lead Dr. Dan Gessler. “The technology continues to grow by leaps and bounds, and at the same time, it’s becoming more easily accessible. I think people will really be amazed by what is possible through simulation today.”
