Abstract
A hybrid meshless method is constructed in this paper for the solution of the second order hyperbolic telegraph equation in two space dimensions with Dirichlet or mixed boundary conditions. The temporal derivatives of the physical quantity included in the telegraph equation are approximated into the finite difference formulae by using the Houbolt method. Based on these formulae, the original telegraph problem is then transformed into the modified Helmholtz equation which is efficiently simulated with the generalized finite difference method. The developed hybrid scheme is mathematically simple and truly meshless. We finally provide three numerical examples including one case with a complicated domain, and all numerical results illustrate the good performance of the developed hybrid meshless scheme.
