FluidX3D is a high-performance lattice Boltzmann method computational fluid dynamics (CFD) application written in C++/OpenCL. It runs on all GPUs and CPUs with exceptional speed and memory efficiency, and includes interactive visualization and benchmarking capabilities.

Use cases

• simulate fluid flow around objects on GPU
• run CFD simulations without expensive licenses
• benchmark GPU and CPU floating-point and memory performance
• visualize fluid dynamics interactively in 3D
• compute forces and torques on bodies in a flow
• run multi-GPU CFD simulations on a single machine
• voxelize STL meshes into simulation grids

When to choose

• you need fast, memory-efficient lattice Boltzmann CFD on any GPU vendor via OpenCL
• you want free-for-non-commercial-use fluid simulation with interactive visualization
• you want to stress-test or benchmark GPUs/CPUs with a real scientific workload
• you need cross-vendor multi-GPU scaling on one node

When to avoid

• you need commercial-use CFD without licensing restrictions (license is non-commercial only)
• you need general-purpose CFD with meshes, turbulence models, or heat/solver features beyond LBM
• you need a library to embed in your own code rather than a standalone application
• your environment lacks OpenCL support
