ABSTRACT:
The world around us is governed by the laws of physics which are captured by equations that model various physics; we solve these equations using numerical methods such as finite element analysis and finite difference methods. In this talk we will explore the use of IA, Machine Learning and Deep Learning to accelerate these engineering simulations. We will describe how we are accelerating our solvers by factors of 10X-100X using Machine Learning in specific physics areas. We have developed an ML-based Partial Differential Equation solver and applied it to accelerate Fluid Dynamics problems and will report our results on our Fluent CFD software. We will report on an end-to-end chip packaging solution using a combination of data-driven and physics-informed neural networks. We have integrated it within our Redhawk/IcePak/Mechanical solutions for Conjugate Heat Transfer. We will describe approaches to support fast design exploration/optimization using ML frameworks. We are also providing ML-enabled assistance in various steps of simulation workflows such as initial meshing, smart sub-modeling, user experience and automati selection fo parameters. We will report on automatically setting the best parameters in Fluent/Live AMG solver. We report on geometry encoding methods to scale our ML methods to any geometry. We will discuss a Fusion model to combine test data with low fidelity simulation data to produce high fidelity simulations. We will also report on a new ML framework to improve the productivity of any ML developer working in the simulation area. Finally, we wil summarize various AI/ML enabled products that are being released this year and in future years.
