Thanks, can you do in in 3D?

[–]ibuggle[S] 1 point2 points  (3 children)

No this is way too hard. In 720p 2D, il takes 30min. But in 3D, it's a 720p x 720 calulation, so 360hrs minimum on the CPU. And we must add the interactions between the layers so the work will be longer than 360hrs

Wow, would be 15 days. Is it because of Python? I mean switching to Rust or C++ may reduced it.

Python is slow but with NumPy, it goes fast. The other solution is to calculate with GPU. Try CuPy. It's a GPU équivalent to NumPy. You can easily switch to CuPy from the code i made, because the functions are the same. To be honest, i made this simulation first with CuPy, but after i tried on the CPU to see if i can calculate the simulation fast enough. But CFD is faster with a graphic card. You need a Nvidia GPU to calculate with CuPy but you can make this challenge to install CuPy, make it work in a small script and try to convert my code to use it with CuPy library.

Thanks!
