We propose a formal expansion of multiple relaxation times lattice Boltzmann schemes in terms single infinitesimal numerical variable. The result is system partial differential equations for the conserved moments scheme. presented nonlinear case up to fourth order accuracy. asymptotic corrections nonconserved are developed equilibrium values and differentials moments. Both expansions coupled co...
In this paper, based on the classical Fourth-Order Runge-Kutta method, the modified FourthOrder Runge-Kutta method is presented for solving nonlinear vibration of axially travelling string system, that is to solve time varying and nonlinear differential equations. The classical Fourth-Order Runge-Kutta method can only be used to solve first-order linear differential equations. Its main idea is ...
In this paper, the C-conforming finite element method is analyzed for a class of nonlinear fourth-order hyperbolic partial differential equation. Some a priori bounds are derived using Lyapunov functional, and existence, uniqueness and regularity for the weak solutions are proved. Optimal error estimates are derived for both semidiscrete and fully discrete schemes. Keywords—Nonlinear fourth-ord...
