NVIDIA Modulus

NVIDIA Modulus is an open-source framework for building, training, and fine-tuning Physics-ML models with a simple Python interface.

Using Modulus, engineers can build high-fidelity AI surrogate models that blend the causality of physics described by governing partial differential equations (PDEs) with simulation data from CAE solvers or observed data. Such AI models can predict with near-real-time latency and for a parameterized design space.

Using Modulus, you can bolster your engineering simulations with AI. You can build models for enterprise scale digital twin applications across multiple physics domains, from CFD and Structural to Electromagnetics.

Key Features

New Model Architectures

Modulus offers a variety of approaches for training physics-based models, from purely physics-driven models like PINNs to physics-based, data-driven architectures such as neural operators.

Modulus includes curated Physics-ML model architectures, Fourier feature networks, or Fourier neural operators trained on NVIDIA DGX across open-source, free datasets found in the documentation.

Training State-of-the-Art Physics-ML Models

Modulus provides an end-to-end pipeline for training Physics-ML models—from ingesting geometry to adding PDEs and scaling the training to multi-node GPUs. Modulus also includes training recipes in the form of reference applications.

Explicit Parameterization

Modulus provides explicit parameter specifications for training the surrogate model with a range of values to learn for the design space and for inferring multiple scenarios simultaneously.


Omniverse Integration

Modulus is now integrated with NVIDIA Omniverse™ via the Modulus extension that can be used to visualize the outputs of a Modulus-trained model. The extension enables you to import the output results into a visualization pipeline for common output scenarios, such as streamlines and iso-surfaces. It also provides an interface that enables interactive exploration of design variables and parameters for inferring new system behavior and visualizing it in near real time.
