What really makes engineering CFD software complicated are things like handling complex geometries with dynamically refined meshes, efficiently solving the resulting linear equation systems at scale and coupling the fluid dynamics to other physical phenomena while retaining numerical stability and accuracy.
This repo is a little old and dusty and likely doesn't build with the latest tools, If you're looking for a version with working build instructions check out this fork: BathBombFluidDynamics by Oliver Curtis which adds some interesting effects. aren't very complicated and are well described in any CFD textbook. Cross-platform GPU fluid simulation Demo. Ultimately, though, all the basic "best practices" for simulations of this kind - staggered grids, higher order derivative approximations, etc. It doesn't use any approximation tricks for square roots etc., so given appropriate floating point semantics (as a physicist I have no clue what the shader language specifies there) you can still get realistic and accurate results by reducing the spatial and time steps, which is easily doable for a small 2D simulation on modern GPUs. 2D Liquid Simulation - GitHub Pages A WebGL fluid simulation that works in. The closest fluid simulation plug-ins I have found are the latest version of Particular or perhaps Newton. Although, it would very likely get overused in every project immediately. I just think it would be a cool effect to use in motion graphics. If I use css such as 'pointer-events: none ' on the object thats covering the canvas the animation will work but then I cant select text or use.

The problem Im having is that if the canvas is below a object the mousemove event for the canvas stops firing. It also uses a first order approximation to the Dirichlet and Neumann boundaries, so that additional error will diffuse throughout the simulation region. The original author is PavelDoGreat and the github can be found here:If Ill. I fully admit I have no idea what Im talking about when it comes to programming. Hi everyone, I have a canvas that is running the Web GL Fluid particle animation. It's just the basic second order central difference.

I didn't check what finite difference stencil or finite volume scheme the code uses, though I presume it's a lower order accurate one that probably has a fair amount of numerical viscosity.
