{"id":98221,"title":"Inviscid AI: Real-Time Physics Simulation For Digital Twins of Built Environments","tagline":"Real-time physics simulation that cut energy costs and accelerate design cycles","body":"TL;DR: We are creating real-time physics simulations \u0026 digital twins of physical spaces. 1000x faster than traditional solvers; fast enough to actually optimize your energy costs, design cycles, and live operations.\n\n---\n\nBuilding operations account for approximately **40%** of **total energy consumption** in the United States and the European Union. Of that, **HVAC** alone eats up roughly **40%,**  making heating and cooling the single largest energy end-use in the built environment. And yet, the physics tools to understand and optimize these systems in real time have never existed.\n\nTraditional CFD solvers take 8-12 hours per simulation. That's fine for final-stage validation. But it means you can never use simulation to answer questions like:\n\n* \"This data center row is running hot. What's the fastest fix that doesn't require new hardware?\"\n* \"Occupancy just spiked on floor 3. What should we do with the HVAC right now?\"\n* \"We're choosing between 40 thermal designs. Can we test them all this afternoon?\"\n\nThese are real-time decisions. You can't wait 12 hours for them. So today, operators guess, over-provision, and leave massive efficiency gains on the table. Not because they don't care, but because the physics was always too slow to be useful at the moment.\n\n**We fix that.** Our engine runs \\~1000x faster than traditional solvers using GPU accelerated numerical solvers or physics-informed neural operators, fast enough to turn simulation from a one-off analysis into a live, continuous control layer over physical systems. \n\n![uploaded image](/media/?type=post\u0026id=98221\u0026key=user_uploads/2566201/c345ead2-296e-43a5-b200-09bb372643eb)\n\nWe've achieved _state-of-the-art_ performance on standard Navier-Stokes benchmarks across multiple physics domains.\n\n![uploaded image](/media/?type=post\u0026id=98221\u0026key=user_uploads/2566201/3fa0a608-633c-4083-bcd9-1ebf3561d634)\n\n![uploaded image](/media/?type=post\u0026id=98221\u0026key=user_uploads/2566201/57760bd4-95fd-4a4b-aeb9-692c04c68cab)\n\nThis isn't a cheaper simulation. It's a fundamentally new capability: **real-time physics-aware control of the physical world.**\n\n### **What This Unlocks**\n\n* **Live Digital Twins:** Connect to your building's sensors and get a full spatial model of airflow, thermal loads, and energy draw - updating continuously, not a static snapshot. Instead of 5 temperature readings, you get the complete picture of what's happening across your entire facility, right now.\n* **Dynamic Optimization:** Your HVAC doesn't need to run on static schedules. With a live physics model, setpoints adjust automatically as occupancy, weather, and equipment state change. We're seeing 15–30% energy reduction - not from a one-time audit, but from continuous, physics-informed control.\n* **Instant What-If Scenarios:** \"What if we move this vent?\" \"What happens if we add 200 servers to this row?\" \"How does this layout perform at peak summer load?\" Answers in seconds, not days.\n* **Rapid Design Iteration:** Test hundreds of thermal, airflow, or structural configurations in the time it takes to run one traditional sim. Explore the full design space instead of picking 3 candidates and hoping.\n\n### **Who This Is For**\n\nWe built InviscidAI to power real-time decisions across any domain where physics matters:\n\n* **Facility Operators:** Optimize HVAC, ventilation, and energy usage across office buildings, warehouses, hospitals, and cleanrooms - dynamically, as conditions change.\n* **Data Center Teams:** Manage thermal loads and cooling in real time. Plan capacity expansions with instant physics feedback instead of week-long simulation cycles.\n* **Cold Storage Owners**: Understand their facility in real time, and prevent thermal failures and product loss.\n* **Hardware \u0026 Manufacturing Engineers:** Accelerate thermal, airflow, and structural design iteration from weeks to hours. Ship better products, faster.\n* **Building Owners \u0026 Developers:** Understand exactly how design choices affect energy performance before breaking ground - and keep optimizing after move-in.\n\n### **Where We're Going**\n\nHVAC and building operations are our starting point. Our end goal is to model all fields of physics - fluid dynamics, thermodynamics, electromagnetics, structural mechanics, and beyond - and deliver real-time digital twins for any physical system. We want every engineer, operator, and designer to have a live, physics-accurate model of whatever they're building or managing. If it obeys the laws of physics, we want to simulate it in real time.\n\n### **Our Ask**\n\nWe're deploying custom digital twins for enterprise clients. We're looking for introductions to:\n\n1. **Facilities \u0026 Operations Teams:** Anyone managing large buildings, campuses, or industrial facilities with high energy costs or thermal challenges.\n2. **Data Center Operators:** Teams dealing with cooling optimization, hot spots, or capacity planning.\n3. **Hardware Engineering Teams:** Engineers frustrated with slow CFD/thermal simulation cycles.\n4. **Building Developers \u0026 Owners:** Anyone who wants physics-informed design and continuous post-occupancy optimization.\n5. **Digital Twin / IoT Platforms:** If you're building monitoring infrastructure and need a real-time physics layer, let's partner.\n\nIf you have a physics problem that you want to solve faster, we want to hear about it.\n\nBook a time here: \u003chttps://calendly.com/kabir-inviscidai/30min\u003e\n\n📧 [kabir@inviscidai.com](mailto:kabir@inviscidai.com) | 📞 +1(408) 303-9627 | 🌐 [www.inviscidai.com](http://www.inviscidai.com)\\\n\\\n\u003chttps://www.youtube.com/watch?v=ISM5gMWZQr4\u003e","slug":"PYD-inviscid-ai-real-time-physics-simulation-for-digital-twins-of-built-environments","created_at":"2026-02-26T22:52:27.034Z","updated_at":"2026-05-25T05:14:11.008Z","total_vote_count":6,"url":"https://www.ycombinator.com/launches/PYD-inviscid-ai-real-time-physics-simulation-for-digital-twins-of-built-environments","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":31023,"name":"Inviscid AI","slug":"inviscid-ai","url":"https://inviscidai.com/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/edd438978013e82ecd281b761baafad0dab9c68e.png","batch":"Winter 2026","industry":"Industrials","tags":[],"search_path":"https://bookface.ycombinator.com/company/31023"}}
