Block-Structured NS LES/WMLES code

[EduardoMolina]

Hello!

First, thanks for sharing this amazing project. Second, sorry if this isn’t the right place to ask this question.

I would like to know if there is an ongoing effort to develop a block structured NS-FV LES/WMLES code able to simulate academic relevant flows, i.e turbulent channel flow, NASA Hump etc.

If yes, could someone please point me to the right direction? If no, do you think the current code could be used as a starting point?

Best,
Eduardo

Hi Eduardo -- thanks for your interest!

We've just started playing around with flows with boundary conditions, e.g., for channel flow:
https://github.com/google/jax-cfd/blob/main/notebooks/channel_flow_demo.ipynb

What sort of numerical schemes do you have in mind for these types of simulation? Would these cases involve irregular or unstructured grids? My guess is that something like imersed boundary conditions would be relatively straightforward as an extension of our current code, but non-rectalinear domains/grids could more challenging.

Just throwing ideas here, but can we possibly explore the use of adaptive mesh refinement? Curious how we can load balance stuff in a TPU+GPU environment
