FluidX3D - A New Era of Computational Fluid Dynamics

With slow commercial #CFD software, compute time for my PhD studies would have exceeded decades. The only way to success was to master #GPU programming, write my own CFD solver from the ground up and turn runtime to days. Now a 10 billion cell simulation (like in the video) runs over night on an 8-GPU server, visualizing hundreds of TeraByte with my #OpenCL graphics engine.

Thanks to the people at Jülich Supercomputing Centre for letting me test their hardware!

I just tested this on my 4 year old midrange pc ( GTX 1660 Super GPU, using the river demo shown here ) and it ran in near real time! ( like 15fps, I wasn't keeping track ) I cant even begin to imagine how much effort it takes to have a entire fluid simulation run at a interactive speed, well done man!
Also your documentation is excellent, I got it up and running in less than 5 minutes.


( ps: If I can figure out how to make my own fluid sims, I'm almost certainly going to use this more than just this one time. )

Here we see excellent visualisations murdered by youtube bitrate.

I cant imagine how long and tedious it took to write your own program for these visualizations! I know almost nothing about physics or science, but I know from experience coding is a very complicated process and this is absolutely impressive!

Don't know about anyone else.... but I'm Navier-STOKED!

[lucamagni]

Fantastic! One of the projects that I follow with more interest!

And this, ladies and gentlemen, is how real scientists flex!

Thank you, it's the work of people like you that inspire and helps with young passionate people that later become field leaders, often times pushing science to it's very limits and thank you, from me as a person as I will now attempt to run a CFD simulation of a crab because no one can stop me now

[davidebic]

Can't wait to take my partial differential equations course next semester when looking at this.

As an aerospace engineering student this is absolutely incredible, thank you for making this

[monkeeseemonkeedoo]

Thank you for making your work available like this! I'm sure it will inspire a lot of people

[claude]

YEsss looks very nice, will try it ASAP.

Bummer to see such a high quality product demo RUINED by Youtube compression! Great work can't wait to try myself

[quillmaurer]

Awesome! I've been looking for accessible CFD for a long time. Have a lot of CAD experience but not much CFD - how easy is this to learn? Does it only output flow visualization, or can it also provide useful numbers for an engineering context like drag and lift forces? For many years I've wanted to evaluate configurations of spoilers or air deflectors on my classic Volkswagen Beetle to try to improve fuel economy, CFD probably wouldn't be the end-all answer but could be a really useful and interesting tool alongside real-world testing (yarn tufts, pressure sensors, and coast-down). Basically combine this with all of Julian Edgar's videos on car aerodynamics.

Just need a $4, 000, 000 graphics card and a copy of this program.

[MrZwulch]

I miss the aerodynamics of a cow simulation in this trailer:(

[herrkunde]

This is really cool! It almost looks like DNS. Are there any plans to incorporate an energy distribution to model heat transfer problems, for example?

[zackazuki]

I can only imagine the rendering time and processing power it took to make these videos

[MonsterJuiced]

Wow you are very generous to do this. When you started GPU programming, how long did it take you to reach this moment of release?

[rxcyoji]

It's amazing! l want to do what you have done one day.

[GatewaySpace]

Do you think we could all start using this in the near future? Could it be ported as a water simulation add-on for Blender? That would be INSANE, you'd get a ton of attention!
