In this post, I'll walk through my implementation of the Volume of Fluid method. The overall motivation is to simulate 3D waves and droplets of water, like this: In practice, this post will mostly d
Motivation So far, we’ve simulated featureless, undulating orange grids, which I find boring. What’s really cool would be an animation of a droplet of water falling into a water surface, including all
Non-trivial CUDA The current snippet of code calling CUDA is: cuda_step<<< 1, 1 >>> This uses only one CUDA thread, and is probably extremely inefficient. To verify this, let’s add some way to time the program. I could use NVIDIA’s nsys, or just the...
There’s a good first CUDA tutorial here: https://developer.nvidia.com/blog/even-easier-introduction-cuda/. Then there are the docs here: https://docs.nvidia.com/cuda/cuda-c-programming-guide/#. The docs describe three levels of the thread hierarchy —...
Motivation In this series of posts, I'll try to simulate waves on a GPU using CUDA. First, I'll describe the exact scope of the project. The goal is to implement some computational fluid dynamics method to solve some fluid dynamics problem - for now,...
