ILG simulation on a 128x256 lattice, particle density of 0.7, obstacles with 25% coverage. The system has periodic boundary conditions and momentum is injected at a constant rate on the left boundary of the system. Red particles that leave the system re-enter the system on the left side as blue particles. The pressure of P=0.0058,0.058, and 0.57 correspond to low, medium and high pressures, respectively.
The "annealed" obstacles come from a previous phase-separation simulation in which the low concentration phase was saved in a file to serve as obstacles for the present simulation.
