The nearly-analytic symplectic partitioned Runge-Kutta(NSPRK)method is a type of finite difference method for solving seismic wave equations.It uses the fourth-or higher-order nearly-analytic discrete(NAD)operators to discretize the high-order spatial derivatives in the Hamiltonian PDEs,and then employs the conventional symplectic partitioned Runge-Kutta(SPRK)method to solve the resulted Hamiltonian ODEs after spatial discretization.
