NEW YORK, NY, Feb 20, 2025 – nTop has acquired cloudfluid, a German company specializing in computational fluid dynamics (CFD) software. With the addition of cloudfluid to its technology stack, nTop presents a comprehensive platform for computational design that transforms how engineers design high-performance products.
CFD involves complex meshing and lengthy run times, making it impractical to use in rapid design iterations. Cloudfluid addresses this challenge with its GPU-native solver technology that predicts fluid flow without the difficulty of creating complex conformal meshes. Coupled with nTop’s implicit geometry kernel, engineers can now iterate on designs in near real-time to create breakthrough products.
“We are hyper-focused on building software that helps engineers go from requirements to design as fast as the latest computing processors allow—that’s the power of computational design,” said Brad Rothenberg, CEO of nTop. “One of the biggest bottlenecks has always been solving the physics—it takes time to mesh and converge on a solution. cloudfluid solves this by integrating directly with our implicit modeling core, bringing CFD into the iterative computational design loop.”
The integration of cloudfluid’s high-speed CFD with nTop’s computational design platform expands applications in aerospace, defense, and turbomachinery, where fluid dynamics are critical. Engineers can now explore complex shapes and improve designs faster. This advancement enhances propulsion, aerodynamics, and thermal management systems. These technologies also tackle the issues of machine learning, where there is often a shortage of curated simulation data. This combination boosts decision-making, speeds up innovation, and improves manufacturing efficiency by allowing the cost-effective creation of high-quality simulation data. This data is essential for training predictive models in digital twins and optimizing designs.
