Mathematics and Computers in Simulation | 1999

Comparison of four software packages applied to a scattering problem

Niels Christian Albertsen; Jean-Marie Chesneaux; Søren Christiansen; Armand Wirgin

We investigate characteristic features of four different software packages by applying them to the numerical solution of a non-trivial physical problem in computer simulation, viz., scattering of waves from a sinusoidal boundary. The numerical method used is based on boundary collocation. This leads to highly ill-conditioned linear systems of equations, such that ensuing results may lose significant digits. The packages under consideration, each of which is based on a specific computer arithmetic, are the following: CADNA, PROFIL, MAPLE and MATLAB.
