RANN: A Neural RANS Closure Model for Physics-Informed Machine Learning on General Geometries
ORAL
–
Publication: FluidAI provides cloud-based real-time machine-learning enabled CFD and Fluid-Dynamics optimization systems for several industrial and commercial applications. The disruptive technology, based on physics-informed deep learning, has already impacted several high complexity simulation and design areas, from high energy plasma physics to complex non-rigid robotics actuation, and is now ready to be brought to bear in the CFD domain. FluidAI can achieve several orders of magnitude speed-up compared to standard CFD solutions, without compromising accuracy, as well as allow for interactive design of complex aerodynamic instruments. The cloud-based solution allows for scalability and ease of use, as well as drop in integration on several existing workflows.
