Hi,
This project looks very ambitious, and potentially very useful for economics researchers. Thanks a lot for working on this.
I just want to share something I have learned solving HJB equation…

Larger PDE solves may benefit from a reverse mode AD and also helps with adding support for neural networks as surrogates or part of training the PDEs themselves, therefore I was wondering what it wou…

## Reason
Multi phase flow is very important physics for some applications and users including @joe61vette
## Design
One possible design is adding additional terms to the Rhie-Chow interpolation…
