We build this mock-up of a gas chromatography simulation to illustrate the applicability of the library to simulations which rely topologies other than regular grids. The video shows how a gas with two substances in solution is pumped through a column filled with activated carbon (indicated by the spherical shapes). The two diagrams on the right show the relative fraction of each substance in the solution. The activated carbon reduces the flow speed, which is why pressure is build up on the bottom of the column, while a vacuum forms at the top. The carbon also absorbs the second substance to a certain degree, which is why it arrives at the top later than the first substance.

For this simulation we placed the cells randomly on the 2D plane and used a Voronoi diagram do determine their shapes. Tiles of these cells were embedded into container cells. The container did act as an adapter for LibGeoDecomp, to which the model appeared to be a regular stencil code.
