News & Events

Our group contributed 3 poster presentations at AGU Annual Meeting 2025. If you are interested in our work, please check out our posters:

NG31A-VR8968A: Du et al., Differentiable Meshfree Framework for Hybrid ML–Physics Forward and Inverse Modeling of Geomechanics and Geophysical Flow Hazards

H43F-VR8718: Lin et al., Differentiable Physics-constrained subsurface inversion with Latent Diffusion model

CIMS Lab at USNCCM-18: Showcasing Advances in Differentiable and AI-Augmented Mechanics

We’re excited to share the strong presence of the Computational Intelligence and Mechanics Systems (CIMS) Lab at the 18th U.S. National Congress on Computational Mechanics (USNCCM), held in Chicago, July 20–24:

• Guo, Binyao et al., Attention-Enhanced Fourier Neural Operators for Robust Constitutive Modeling of History-Dependent Nonlinear Materials [Abstract]
• Lin, Zihan et al., A Latent Diffusion Model-Coupled Differentiable Physics Simulator for Inverse Modeling of Heterogeneous Media [Abstract]
• Du, Honghui et al., A Differentiable Meshfree Method for Nonlinear Mechanics and Geomechanics Modeling [Abstract]

Happy to share two recent preprints from my research group:

1. History-Aware Neural Operator (HANO) for robust constitutive modeling of path-dependent materials (https://arxiv.org/abs/2506.10352)

2. JAX-MPM, a learning-augmented differentiable meshfree framework enabling GPU-accelerated Lagrangian simulation and geophysical inverse modeling (https://arxiv.org/abs/2507.04192)

HANO aims to overcome key limitations related to loading resolution dependence and internal variable representations in path-dependent materials modeling. JAX-MPM provides a unified, high-performance framework for forward and inverse simulations in geomechanics and geophysics, in which we particularly focus on complex scenarios involving large deformations, inelastic responses, and fluid-solid interactions.

Both frameworks are fully differentiable and seamlessly integrate with modern deep learning platforms.

Feel free to explore and connect for further discussions!

Dr. He presented recent advancements in a differentiable Eulerian–Lagrangian framework (JAX-MPM) for nonlinear mechanics and landslide hazard modeling at the 2025 ASCE Engineering Mechanics Institute (EMI) Conference in Anaheim, California, from May 27–30, 2025.

As of March 30, 2025, our group is officially named the Computational Intelligence and Multiphysics Simulation Lab (CIMS Lab) — formerly known as the Intelligent Computational Mechanics Group (InCOME).

This name change reflects our broader and evolving vision: to advance the integration of artificial intelligence, physics-informed machine learning, and high-performance simulation science in addressing complex multiphysics challenges across engineering, geoscience, biomechanics, and beyond. Thank you for your continued support — we’re excited for the journey ahead!
 

The project is about leveraging state-of-the-art Generative AI techniques combined with mesoscale modeling to accelerate the discovery and optimization of novel polymer materials. We sincerely thank 3M and our collaborators for their generous support.

I was pleased to share our recent research on Differentiable Solid Mechanics and Geophysics with students and colleagues during my visit to Singapore in September. The talk was titled "Neural-Integrated and Data-Driven Approaches for Computational Modeling in Solid Mechanics and Geophysics." I am grateful for the warm invitations from NUS, NTU and A*STAR.
