Physics-Informed Neural Networks with NVIDIA Modulus: Application to external flow problems
Par Niki Loppi, AI/HPC solutions architect, Nvidia
In this talk, we will review the fundamentals of Physics-informed Neural Networks (PINN) and explore the capabilities of NVIDIA Modulus framework for solving external flow problems that are common in various aero/hydrodynamic applications. Specifically, we will focus on how Modulus is able to train parameterised PINNs which, after training, can be used simulate different flow conditions almost instantaneously. Furthermore, we will also present how users can undertake unsteady (time-dependent) simulations using the moving time-window approach. Finally, we will show results for a parameterized unsteady case which demonstrates that PINNs are able to capture temporal dynamics across a range of Reynolds numbers.
