Abstract

This paper presents the application of the radial basis functions (RBF) for solving a set of non-linear hydrodynamics model for marine environments. Two different techniques, namely compact support and multizone decom- position, are used to improve the conditioning of the resultant coefficient matrix which is a full matrix due to the use of the global radial basis func- tions. The idea of the compactly supported radial basis function (CSRBF) is to reduce the full matrix to a banded sparse matrix. The multizone approach is similar to the commonly used domain decomposition. The re- sulting sparse or smaller matrix has shown
