Wrote first article of my blog about a development of fluid simulation. But it's written in Japanese, please google translate. nalog.dev/blog/two-way...

First result of 3D fluid simulation while it is not stable yet. Fluid surface is rendered with Marching Cubes. #bevy #fluidsimulation

The very first step for rendering 3d fluid surface with Marching Cubes algorithm: draw a single triangle in a indirect draw pipeline.

Opened my own blog site nalog.dev. There are only a few demos made with #bevy and written only in Japanese for now though.

Although it runs at around 10 FPS, at high resolution (2048x2048 grid), you can see fine and interesting structures in the wake of the tube. #bevy #fluidsimulation

During a renewal of examples in bevy_eulerian_fluid, I made an example for Karman vortices. #bevy

narasan49.bsky.social @narasan49.bsky.social · 15/04/2026

More flexible fluid setup using fluid source component I've being implementing. This is a dam breaking setup example. #bevy

narasan49.bsky.social @narasan49.bsky.social · 13/04/2026

The simulation is now 1.3x faster with the multigrid method. Down to 3.0 ms at 512x256 resolution on a Snapdragon GPU. #bevy

Also, the simulation became over 2x faster (8.5 ms to 4.0 ms for 512x256 simulation!) on Snapdragon's Adreno GPU while improving mass conservation.

Mass conservation is being much improved with Gauss-Seidel method for projection and Fast Iterative Method for level set reinitialization. #bevy

On the way to implementing Particle Level Set. Particles are passively advected by the fluid velocity currently. #bevy

Started working on improving mass conservation of fluid simulation. Currently prototyping a particle levelset method in python.
