## Model Details

Emmi AI developed and released **Anchor-Branched Universal Physics Transformers** (AB-UPT) model for aerodynamics simulations. The model has been trained on DrivAerML dataset. 

It is expected that the user will provide input geometry similar to the ones from the DrivAerML dataset.

## How to use

We provide a standalone GitHub repository with relevant tutorial code on how execute inference. The corresponding repository can be found here: https://github.com/Emmi-AI/AB-UPT
