# GeoPT: Scaling Physics Simulation via Lifted Geometric Pre-Training

[**Project Page**](https://physics-scaling.github.io/GeoPT/) | [**Paper**](https://huggingface.co/papers/2602.20399) | [**GitHub**](https://github.com/Physics-Scaling/GeoPT)

GeoPT is a unified pre-trained model for general physics simulation based on lifted geometric pre-training. It bridges the geometry-physics gap by augmenting geometry with synthetic dynamics, enabling dynamics-aware self-supervision without the need for expensive physics labels.

## Key Features

- **Data Efficiency:** Reduces labeled training data requirements by 20–60% across diverse physics simulation tasks.
- **Scalable Self-Supervision:** Generates millions of training samples quickly, significantly faster than traditional physics supervision.
- **Strong Scaling:** Performance consistently improves with larger models and more training data.
- **Generalization:** Generalizes across diverse physical systems (fluid and solid mechanics) by reconfiguring the dynamics condition as a "prompt".

## Usage

Concrete usage instructions, including environment setup and scripts for fine-tuning GeoPT on various industrial-fidelity benchmarks (such as AirCraft, Cars, and Ships), can be found in the [official GitHub repository](https://github.com/Physics-Scaling/GeoPT).
