Turbulent fluid flow in a box with obstacle.

- This is a demo simulation, demonstrating the current capabilities of my CFD desktop application.
I recently rewrote my previous application. It is now tremendously faster and has a cooler visualization style.
I expect to publish an early version of the program, as soon as I have the following implemented:
mesh support, result analysis, GUI simulation setup and more visualization options.
If you are wondering, why the fluid jet wiggles in the beginning. I believe it's due to a shockwave bouncing around the box, from the immediate acceleration of the fluid in the inlet.
Pretty cool! you going to release the code or is this aiming to be commercialized
Thank you! I am kinda hesitant to release the code, but you will be able to download the compiled application for free.
You have a super cool channel btw :) I really want to get into ML for CFD and shape optimization at some point.
Hello, awesome, I am curious about how you are achieving the 50xrealtime in the rendering, thanks
Hi, thank you! What exactly do you mean? The 50x refers to the video speedup compared to the original realtime/simulation and rendering speed. It's rendered using a fast volume rendering technique.
Hello, okey, so you have recorded the simulation with some program and played it back at 50 x.
On the other hand, could you share what fast volume rendering technique have you used, indicating paper or some technical document? I am very interested in volume rendering
Thanks
@@alejandrol9358 Sure! This resource was really helpful: subscription.packtpub.com/book/game-development/9781788296724/1/ch01lvl1sec08/7-gpu-based-volume-rendering-techniques
Later I hacked together a very basic and slower ray based volume renderer, but it handles high transparency at high resolution better. The mushiness In the video is because of that transparency problem.
What is this? Is it accurate?
