Orientational order in confined systems of self-driven spinners

We investigated large systems of self-driven spinners confined over a substrate through direct numerical simulation of 3D hydrodynamics. Our results demonstrated that these systems generate unique flows from which spatial and orientational order emerges. We showed that a transition in particle orientation accompanies the appearance of crystallinity as the packing fraction is increased. Further exploration revealed a rich, tunable state space, offering insights into the biophysics of natural microswimmers with rotational motion as well as into the design of synthetic spinner systems. This is a dataset of the simulations performed to generate the figures in the corresponding paper. The directories are organized by figure and subfigure. Raw simulation data are in the KAPSEL UDF format; please refer to the KAPSEL-DNS website and user manual for further details on this format. In addition, postprocessing and analysis scripts to read raw data, perform postprocessing calculations, and generate figures are supplied.
