3D computational models explain muscle activation patterns and energetic functions of internal structures in fish swimming
Fig 1
(A) and (B) are the meshes without body deformation for the eel and mackerel, respectively. Flow fields in the middle coronal planes (z = 0) of the eel (C) and mackerel (D) models in the laboratory frame. The arrows indicate the velocity direction and the colors represent the magnitude of the velocity. Only flow speeds greater than 0.02 in nondimensionalized units are shown in color.
