主 题:Viscous and nonviscous wave equations FDMs ADI methods convergence
摘 要:The numerical solutions of two-dimensional(2D)and three-dimensional(3D)nonlinear viscous and nonviscous wave equations via the unified alternating direction implicit(ADI)finite difference methods(FDMs)are obtained in this *** making use of the discrete energy method,it is proven that their numerical solutions converge to exact solutions with an order of two in both time and space with respect to H^(1)-*** results confirm that they are relatively accurate and high-resolution,and more successfully simulate the conservation of the energy for nonviscous equations,and the dissipation of the energy for viscous equation.
