We wrote a Tesseract-JAX demo on using differentiable programming to optimize fluid simulations. The goal is to find initial conditions that evolve into a target pattern (the Pasteur Labs logo) using JAX-CFD and gradient-based optimization.

Check it out [here](https://docs.pasteurlabs.ai/projects/tesseract-core/latest/content/demo/cfd-optimization.html)!

The tutorial covers:

- Building differentiable fluid simulators using JAX-CFD wrapped in a Tesseract container
- Leveraging gradient-based optimization with scipy for complex physical simulations
