Inacby is an interactive experience of the evolution of a complex bicontinuous structure of two immiscible fluids. When touching the display of your device, the structure evolves locally in time either on top of the camera image of your device or on a white background. The evolution is driven by the surface tension of the interface of the two fluids, which results in a continuous reduction of the interface area and leads to self-similar structures. The process was mathematically described by a Cahn-Hilliard equation, which was numerically solved by an adaptive Finite Element Method on the high performance computer JURECA at Jülich Supercomputing Centre. The resulting complex 3D structure was cut off at the fluid-fluid interface, then sliced at five distinct level-lines which were projected into a plane to obtain a 2D image for each timestep of the simulation.
At the menu-screen you decide whether the fluids mix or demix, whether the camera-image is used as background and whether a screenshot-button will be displayed. Afterwards you select one of four anisotropies for the two liquids: sphere, cube, pyramid and tetrahedron.
After loading of the respective image-set is completed, you can evolve the structure locally by touching the display.
