Step #2: Darcy Flow example with Neural Operator

Physics-Informed Machine Learning with NVIDIA Modulus (Latest Version)

In this tutorial, you will use Modulus to set up a data-driven model for a 2D Darcy flow using the Fourier Neural Operator (FNO) architecture. In this tutorial, you will learn the following:

  • How to load grid data and set up data-driven constraints

  • How to create a grid validator node

  • How to use Fourier Neural Operator architecture in Modulus


FNO surrogate model for 2D Darcy flow
