Lattice Boltzmann Simulation using a NVidia GTX680

Lattice Boltzmann Method has been used to simulate a fluid in a porous medium which was emulated with multiple spheres. The upper real time video show the results for 17 small spheres. A grid of 512×256 cells was selected, the same number of pixels have the images. The color represents the modulus of the speed. The algorithm was tested on a 5 core CPU and two GPU, a GeForce GT525M with 96 cores, and a GTX680 with 1536 cores.
