Why Two‑Phase Direct‑to‑Chip Cooling is Reaching a Tipping Point
May 19, 2026
Modelon & University of Maryland Researchers to Present Findings at Upcoming Conference Artificial intelligence and high-performance computing (HPC) are fundamentally reshaping the way data centers are designed. Power densities continue to rise, thermal margins are tightening, and workloads are becoming more dynamic and less predictable. HGX H100 racks introduced in 2022 consumed around 40–60 kW, […]
How to Do Weather File Sweeps in Modelon Impact
May 12, 2026
A customer told us something recently that stuck with me. They were evaluating how a data center design would perform across climates. Hot and humid. Cold and dry. Different cities, different weather years. The kind of analysis you have to do if uptime, efficiency, and resilience matter. Technically, they were getting it done. Practically, it […]
AI Liquid Cooling at System Scale
April 29, 2026
A recent presentation at Data Center World highlights how system simulation is becoming a critical capability for designing, procuring, and operating AI data centers. AI has been embedded in digital infrastructure for years, quietly powering services like recommendation engines, security systems, and automation. What changed in late 2022 was accessibility. With the rise of generative […]
5 Questions to Ask Before Trusting AI-Related Simulation Results
April 16, 2026
AI can now generate simulation models from natural language prompts. It can derive equations, write code, configure experiments, and produce results. For engineers evaluating these capabilities, the interesting question is no longer, “Can AI do it?” It almost always can. The harder question is: “Should I trust the result enough to make a decision?” That […]
Data Center Compliance: How to Validate Cold Plate Liquid Cooling Against ASHRAE Guidelines Virtually
February 20, 2026
Today we are beyond the stage where liquid cooling is viewed as experimental, and it stands as a mainstream architectural choice for high density data centers. Cold plates, coolant distribution units (CDUs), rear door heat exchangers (RDHx), and even early two-phase systems are becoming standard topics of engineering conversations. Yet as more operators push beyond […]
Digitally Engineering the Future of Data Centers
January 27, 2026
A Conversation with Simulation Pioneer Michael Wetter As data centers scale at an unprecedented pace—driven largely by AI, cloud services, and high-density computing—the industry is confronting a new level of complexity in energy demand, cooling strategies, and the need for near-perfect uptime. Few people understand this challenge better than Dr. Michael Wetter, a leading expert […]
Turning Frost into Warmth: A Data Center Holiday Story
December 16, 2025
As the year winds down, we found inspiration far from our usual engineering corridors in a quiet little town near the North Pole. It’s a place where winter never takes a break, where lights twinkle through long nights, and where warmth is more than comfort—it’s community. This year, our team imagined a story set there. […]
Simulating Thermal Fluids: Powering Innovation Through Virtual Design
November 12, 2025
Complexities of Thermal Fluids From power generation and HVAC systems to electric vehicles and data centers, thermal fluids are central to how energy moves and systems perform. Their behavior determines efficiency, reliability, and sustainability—but it’s far from simple to predict. Real-world thermal-fluid systems are inherently nonlinear and operated dynamically, with temperature, pressure, and flow intricately […]
