The WaterLily.jl article is now available on Computer Physics Comms!

@gabrielweymouth.bsky.social and I review our CFD solver's design, performance, accuracy, and also show some very cool examples (like the one below). Check it out!

Friends, I watched an AI agent complete my students' coding exercises in real-time, and I'm shook 🤯
I tested Perplexity's Comet browser on a Jupyter notebook with eigenvalue problems I assigned to my class… (video at the bottom of this thread)

Slides for the talk avaliable here!

I'm loving this quarto + reveal.js for creating html presentations. Now that's portable!

Tomorrow at noon, I will be presenting at EFDC2 in Dublin! I will talk about our new mesh-free SINDy framework, collaboration with M. Gao and N. Kutz, for system dynamics identification on unstructured, scarce, and noisy data

Reminds me that I need to start on the slides...

Want to see what the flow past a semi-infinite array of randomly shifted and scaled circles looks like? I did too!

Code is modified from the examples here: github.com/WaterLily-jl...

FastFlows focuses on accelerating scale-resolving turbulent flow simulations combining #CFD, #HPC, and #ML. This enables the integration of such simulations into rapid industrial design cycles, providing accurate and physical solutions with reduced turnaround time.

Today’s vibecode achievement using @gabrielweymouth.bsky.social WaterLily. We went from 10 cylinders to 100 in no time at all; all on a standard laptop #vibecoding #julia #waterlily

Makie v0.24 is out! One of the biggest architectural updates yet—bringing better performance, cleaner internals, and new plotting capabilities. A big step toward Makie 1.0. makie.org/website/blog...
#JuliaLang #OpenSource #Visualization #Plotting #HPC #MakiePlots #WGLMakie #Makie
Makie v0.24 focuses on a comprehensive overhaul of our internal architecture, specifically replacing Observables in our backend code with a more robust system. This fundamental change touches nearly every component of the codebase, making it one of our most ambitious refactoring efforts to date.

I don't believe TOCs for slides, so that's fine by me. But I haven't given Typst a try yet, it's in my long To-do list..

making #quarto slides can be a bit painful, but the end result is amazing. Feels like #Beamer, but it comes with the benefits of #markdown and #html

LLMs with uncertainty quantification output with be nice too

ha, indeed! It was a gif.. nevermind.. thanks for the heads up!

v1.4.0 includes a new set of performance improvements and features such as
- Explicit LES subgrid-scale models
- Custom user-defined function that is called during every time step
- Easy to run an co-visualize with the new routine, viz!
- Custom dynamic boundary conditions and body forces
