RANS-PINN based Simulation Surrogates for Predicting Turbulent Flows

no code implementations9 Jun 2023 Shinjan Ghosh, Amit Chakraborty, Georgia Olympia Brikis, Biswadip Dey

Physics-informed neural networks (PINNs) provide a framework to build surrogate models for dynamical systems governed by differential equations.

Improving Gradient Computation for Differentiable Physics Simulation with Contacts

1 code implementation28 Apr 2023 Yaofeng Desmond Zhong, Jiequn Han, Biswadip Dey, Georgia Olympia Brikis

We find that existing differentiable simulation methods provide inaccurate gradients when the contact normal direction is not fixed - a general situation when the contacts are between two moving objects.

Differentiable Physics Simulations with Contacts: Do They Have Correct Gradients w.r.t. Position, Velocity and Control?

1 code implementation8 Jul 2022 Yaofeng Desmond Zhong, Jiequn Han, Georgia Olympia Brikis

In recent years, an increasing amount of work has focused on differentiable physics simulation and has produced a set of open source projects such as Tiny Differentiable Simulator, Nimble Physics, diffTaichi, Brax, Warp, Dojo and DiffCoSim.
