Numerical implementation based on the Cosserat rod model can effectively solve for dynamic deformations of slender rods, including bending, stretching, twisting, and shearing, as well as interactions with complex environments, such as contact and friction. To solve for the dynamic deformation of magnetically actuated flexible sheets, the sheet is equivalent to two identical slender rods with the same bending stiffness and total mass. Utilizing the PyElastica library, this code implements the deformation of magnetic sheets driven by a given magnetic field and introduces interactions with a rigid substrate.
