# [HNanoSolver](https://youtu.be/W5Qsye3BMng)
> This is a project used to learn Fluid Dynamics and GPU acceleration through Cuda.
- **HNanoSolver**, All in one node computing a quantity advection by a divergence free velocity field on the GPU.
- **HNanoProjectNonDivergent**, Compute a Divergence free velocity field on the GPU.
- **HNanoAdvect**, Advect any float fields on the GPU.
- **HNanoAdvectVelocity**, Advect any vector field on the GPU.
- **HNanoViewer**, Standalone app to visualize VDBs and kernels without having to relaunch Houdini.
# Warning !
> Very Early Development
This repo is undergoing rewrite very often and might not compile from time to time.
Feel free to check the [Open Issues](https://github.com/ZephirFXEC/HNanoSolver/issues) for more details.
# How to Build :
## Windows :
> Make sure HFS is set in your PATH.
- `git clone https://github.com/ZephirFXEC/HNanoSolver`
- `cd HNanoSolver && mkdir build && cd build`
- `cmake -G "Visual Studio 17 2022" -T v142`
It will generate Visual Studio solutions files that you can use to Compile & Run.
## Linux :
> Tested on Ubuntu 24 using GCC 13.3 and CUDA 12.8
- `git clone https://github.com/ZephirFXEC/HNanoSolver`
- `cd HNanoSolver`
- `mkdir build && cd build`
- `cmake -DCMAKE_CUDA_COMPILER:FILEPATH=/usr/local/cuda-12.8/bin/nvcc -DCMAKE_CUDA_FLAGS:STRING="-O2 -g -DNDEBUG -fPIC" ..`
> if any errors here, make sure to have $HFS set, and the right NVCC compiler
- `make`
> if any errors related to AVX / Cuda compilation it's probably due to an incompatibility between GCC and NVCC
