Simulated Cyanotype Chemigrams...

Lately I've been revisiting my old fluid sim toolset which started out as part of my toxiclibs Java libraries (2007/8, based on Jos Stam's research, also previously mentioned in this thread[1]), then ported & expanded it for #Houdini in 2016, then ported again to TypeScript/GLSL (via https://thi.ng/shader-ast in 2019) and been messing around with it on & off ever since... Fluidsims are just so mesmerizing to work/play with and can be taken into so many interesting directions!

I also always loved the watercolor cover designs by Gabriella Holmström for The Memoir[2] series on Hypnus Records and wanted to create similar abstract structures/constellation, albeit with simulated fluids... Stills/snapshots, but showing traces of their creation process.

Attached are a few variations of this system (already collected again hundreds which I have to still curate). Each piece is starting with just 4 drops in always the exact same locations (diamond-shaped layout in the center), but each variation is evolving differently due to randomized concentrations and simulation coefficients, therefore resulting in many different diffusion behaviors and outcomes... Some of the pieces which exhibit more viscous fingering[3] almost remind me of Hokusai's Great Wave[4]...

I will be offering sets of unique prints/cards of these via my shop soon. Also still researching feasibility of integrating interactively created variations in the shop (also for other artworks/collections of mine).

@wavesculptor @noah I _love_ fuid sims! Brings back good ol' dear memories to this project of mine:

So, I finished making my fluid sim gift on ESP32!

Please excuse my nails, I was literally working with bitumen and managed to clean it off my hands, but it started to hurt scrubbing

Over the past two months I've been actively revisiting, updating/extending and now close to finishing this 1.5 year long journey... The actual journey has been much longer, been toying with (faux) fluid sims since ~2007...

A 50 second preview of one of my fave variations, best enjoyed fullscreen... Tried to achieve some molten, dichroic/irridescent glass & oilfilm aesthetics here, but there're over a dozen of other very different routes/styles possible too, with 25+ parameters to tweak the simulation and look & feel...

Made with https://thi.ng/shader-ast & https://thi.ng/shader-ast-stdlib

#ThisMonthInFluiddyn - Nov 2024 edition

* #FluidDyn, #FluidSim, #FluidImage now works with #numpy 2 and #mpi4py 4.0.

* #Spack packaging recipes

* #Apptainer and #Guix packaging for FluidSim

https://foss.heptapod.net/fluiddyn/fluidsim/-/tree/branch/default/doc/apptainer?ref_type=heads

https://foss.heptapod.net/fluiddyn/fluidsim/-/blob/7e52e7bed240665823e04e9f5f8a1fae7d787d06/doc/examples/clusters/gricad/README.md

* Basic support for #Jax is part of #Transonic with v0.7.x

* #FluidImage v0.5.x has a number of improvements, such as work towards matching #UVmat (the MATLAB #PIV suite), new executors and a command `fluidimage-mean`

So much to do, but can't stop watching & hacking on this pseudo fluid sim every now & then... 🤩 Probably will develop this further into a tutorial for https://thi.ng/shader-ast

🔹#FluidSim our #CFD package also gets pre-compiled #Pythran extensions in wheels!

🔹#FluidImage the scalable #PIV package gets its first release in many years, also gets wheels! Heads up for another minor release soon, with breaking changes:

https://fluidimage.readthedocs.io/en/latest/changes.html#release-notes

🔹All this was made possible by the new #Meson support in #Transonic

https://transonic.readthedocs.io/en/latest/packaging.html

and a bit of CI/CD stuff powered by #cibuildwheel
