FluidX3D runs lattice Boltzmann flow simulations directly on the graphics card, from Nvidia, AMD or Intel, so it reaches grids of hundreds of millions of cells on a desktop PC. It imports geometry from STL files, computes forces and torques on bodies, supports free-surface flow, thermal convection, LES turbulence and moving boundaries, and renders results live or exports to VTK. It suits teaching, research and quick aerodynamic checks. Limitation: commercial use is not allowed, and set-up is done by editing C++ code rather than through a GUI.
