Supplemental Material for "Shear-Driven Flow of Athermal, Frictionless, Spherocylinder Suspensions in Two Dimensions: Particle Rotations and Orientational Ordering," by T. A. Marschall, D. Van Hoesen, and S. Teitel The Supplemental Material consists of a set of animations showing the shearing of the configurations whose snapshots are shown in Fig. 5. Note, the systems start in a random initial configuration which contains many unphysically large particle overlaps. Colors are used to help distinguish different particles but have no other meaning. In the list below the file name of the animation is followed by a description of the system shown. m1-simpleshear_a4p905dg1e-06.mp4 Animation of the shearing of the configuration shown in Fig. 5(a). A size bidisperse system of spherocylinders of alpha=4 at packing phi=0.905 and strain rate gdot=1e-6. The total number of particles is N=1024. m2-simpleshear_a01p845dg1e-06.mp4 Animation of the shearing of the configuration shown in Fig. 5(b). A size bidisperse system of spherocylinders of alpha=0.01 at packing phi=0.845 and strain rate gdot=1e-6. The total number of particles is N=1024.
