   2D Lattice Boltzmann
  I think this is the right place to ask this. I am implementing the D2Q9 lattice from the lattice Boltzmann method on the GPU using GLSL. I successfully got the method running on the CPU, but the GPU is giving me fits. Logically it appears I am doing the same thing as on the CPU. Is there anyone here who has implemented a basic version of the lattice Boltzmann method on the GPU? I think if I could talk top someone who has a successful implementation I might be able to figure out what's wrong (currently the density just keeps dropping). Thanks,Patrick
