Is 12 steps to Navier Stokes a good start? I have done all the modules, wrote all the code by myself (except for the plotting part which I had literally no experience in) and I am trying to solve some random problems in the J P Holman heat transfer book. Then I am thinking of going through the Application part of Anderson CFD.
Project mention: Show HN: Elodin – A better framework for physics simulation | news.ycombinator.com | 2024-03-06You are completely correct; right now it is just mechanics that we have built out. But, there isn't any theoretical reason you couldn't use this framework for other types of simulation. In particular, the Monte Carlo runner is super flexible. Since we are based on JAX you can utilize a ton of the tooling that others have built in the physics space like https://github.com/tumaer/JAXFLUIDS or https://github.com/DifferentiableUniverseInitiative/jax_cosm... . The goal right now though is pretty firmly focused on controls engineers and their needs, but we envision this becoming broadly used.

TIL about Anosov flows?
Project mention: Vitalik Buterin wants Bitcoin to experiment with layer-2 solutions, just like Ethereum | /r/CryptoCurrency | 2023-07-10Although most apps are currently in beta, bitcoin supports something called discreet log contracts (DLCs) over lightning. These are hidden or scriptless scripts with little scope for exploits which enable things like derivative contracts, financial products and any kind of "smart contracts" between multiple parties. RGB and Taproot Assets are client-side validation protocols for private smart contracts (no premined VC tokens).
Project mention: Simulating Fluids, Fire, and Smoke in Real-Time | news.ycombinator.com | 2023-12-19I think the curl noise paper is from 2007: https://www.cs.ubc.ca/~rbridson/docs/bridson-siggraph2007-cu...
I've used the basic idea from that paper to make a surprisingly decent program to create gas-giant planet textures: https://github.com/smcameron/gaseous-giganticus
