Fluid in Sierpinski Carpet

Enjoy the low-velocity fluid flow visualization in fractals. The fluid is transported through the Sierpiński carpet geometry. It has been originally published in Polish monography about porous media (figure 9.3 at page 159 in the book). If there is any interest in that I will post more results here (I made some variations, i.e. flow at different levels of the fractal etc.)

Fig: The fluid flows from left to right and it is accelerated by external force (like gravity but it is horizontal here). I applied periodic boundaries at horizontal and vertical walls. The solver used is the Lattice Boltzmann Method (my own code used here).
