NVIDIA Modulus

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

Modulus empowers engineers to construct AI surrogate models that combine physics-driven causality with simulation and observed data, enabling real-time predictions. With generative AI using diffusion models, you can enhance engineering simulations and generate higher-fidelity data for scalable, responsive designs. Modulus supports the creation of large-scale digital twin models across various physics domains, from computational fluid dynamics and structural mechanics to electromagnetics.

Use Modulus to 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, and 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.
