【Abstract】 The dynamical study of a superlong elastic slender rod plays an important role in analyzing many properties of a DNA such as its stability and equilibrium. In order to provide a convenient environment for the post processing of the numerical results in studying the dynamical properties of a DNA, a differential/agebraic equation system is given in this paper to describe the surface of a super-long elastic slender rod.. A symplectic algorithm is provided to solve the equations and a practical example is given as an application of the graph post processing model.更多还原
