Abstract

© 2020 International Association for Mathematics and Computers in Simulation (IMACS) We consider the application of the Kansa-radial basis function (RBF) collocation method to two-dimensional fourth order boundary value problems (BVPs). The presence of two boundary conditions makes it necessary to use a second set of centres corresponding to the second boundary condition. One option is to take these centres on the boundary but at different positions to the original boundary centres. A second option is to place them on a curve surrounding the physical boundary of the problem under consideration. The two approaches are applied to several numerical examples and their results are compared and analysed.
