Individual velocity vectors are represented with red arrows, individual mesh strain vectors with green arrows. The large blue and black arrow are the global mean velocity and global mean mesh strain vector respectively. The corresponding derived MOSES mesh is shown on the right of the arrow plots in black. Bar: 100 μm.
