Figure 30:

Eulerian velocity field and deformations of the fully dynamic version of the elastic band benchmark (Section 4.5) at t = 0.02 s (a), t = 0.1 s (b), t = 0.34 s (c), and t = 0.46 s (d). Each of these time slices corresponds to a different characteristic deformation: (a) near initial configuration; (b) early deformation; (c) largest deformation; and (d) right before the structure enters another period of oscillation. Note that the Eulerian velocity field u(x, t) corresponds to the velocity of whichever material is located at position x; it describes the velocity of the fluid as well as the structure. The color corresponds to the magnitude of the velocity at each spatial point x.
