RBF-PS method and Fourier Pseudospectral method for solving stiff nonlinear partial differential equations

PP: 55-61
Marjan Uddin,
Radial basis function based meshless method is compared with Fourier pseudospectral (FPS) methods for stiff nonlinear partial differential equations with a particular emphasis on the comparison of two methods. Fourth-order Runge-Kutta scheme is applied for temporal discretization. The numerical results indicate that RBF meshless method can be more accurate than standard Fourier pseudospectral method for many nonlinear wave equations.
