摘要

Purpose - The purpose of this paper is to present a numerical solution of a family of generalized fifth-order Korteweg-de Vries equations using a meshless method of lines. This method uses radial basis functions for spatial derivatives and Runge-Kutta method as a time integrator and exhibits high accuracy as seen from the comparison with the exact solutions. Design/methodology/approach - The study uses a meshless method of lines. This method uses radial basis functions for spatial derivatives and Runge-Kutta method as a time integrator. Findings - The paper reveals that this method exhibits high accuracy as seen from the comparison with the exact solutions. Originality/value - This method is efficient method as it is easy to implement for the numerical solutions of PDEs.
