Maze Solving with CFD

Application You already know that Computational Fluid Dynamics (CFD) is great at solving fluid dynamics problems, but did you also know it is able to literally solve mazes too?

Symscape has fun demonstration of the use of CFD to solve mazes.

With the maze created in Caedium I manually added inlet and outlet pipes and then united all the volumes into a single watertight flow volume. I set up the physics in the usual way by assigning air as the substance to the flow volume and setting the boundary conditions, i.e., walls for all faces except the inlet and outlet.

Fluid being fluid it will trace the shortest unobstructed path through the maze, so I setup two views to show iso-surfaces of velocity magnitude and velocity vectors within the flow volume. Then I ran the simulation.
