GoldSim Has Joined the Datacor Family of Solutions

Posted by Rick Kossik

After more than 25 years of building simulation software for some of the most complex, high-stakes problems in engineering, science, and business, we are taking an important next step. GoldSim Technology Group has been acquired by Datacor, and I wanted to share what that means for our customers and community. 

Beyond Deterministic Hydraulics: Introducing the EPANET-GoldSim Bridge

The EPANET-GoldSim Bridge is now available, offering a simple way to leverage GoldSim’s simulation capabilities for water distribution system analysis. This Windows DLL enables users to embed an EPANET hydraulic engine directly within a GoldSim model, bridging the gap between standard hydraulic modeling and probabilistic systems simulation. By integrating these two platforms, organizations can move beyond single-scenario analysis to truly quantify risk and reliability across their networks.

Why Connect Them?

While EPANET is the industry standard for hydraulics, it's typically used for deterministic analysis. Integrating it with GoldSim allows you to:

• Quantify Uncertainty: Run thousands of realizations to see how demand fluctuations or equipment failures impact system pressures.
• Test Complex Logic: Use GoldSim's control elements to drive pump speeds, valve settings, and demands at every timestep.
• Track Performance: Monitor hydraulic head, flow, and even real-time pump power/efficiency to calculate operating costs.

Integrating EPA SWMM with GoldSim for Stormwater Quality

Combining hydraulic modeling with system-level simulation allows for a more detailed look at stormwater treatment. I recently built a bridge to link EPA SWMM with GoldSim to handle both complex water routing and probabilistic contaminant transport in a single model.
