Lattice Boltzmann Method (LBM) - Vortex street around a spaceship

I’ve been playing around with a LBM model ! During the video, the Reynolds number is increased from 10 to 10 000, then decreased back to 10. Model : Lattice Boltzmann method with Multiple Relaxation Time (LBM-MRT) Dye : Semi-Lagragian method, with RungeKutta3 discretization and bicubic interpolation. Code : - Host : PYTHON - Computation : OPENCL on GPU (GeForce GTX 970) - Graphics : OPENGL (with OpenCL interop)
