Spectral approach for improving the Ill-conditioning of the method of fundamental solutions
O método das soluções fundamentais, em inglês, method of fundamental solutions (MFS), é um método para solução de problemas de valor de fronteira de equações diferenciais com derivadas parciais. O método pertence à classe dos métodos que não necessitam de discretização do domínio, evitando, dessa …

A Time Integration Method of Approximate Particular Solutions for Nonlinear Ordinary Differential Equations
<p>We consider a time-dependent method which is coupled with the method of approximate particular solutions (MAPS) of Delta-shaped basis functions and the method of fundamental solutions (MFS) to solve nonlinear ordinary differential equations. Firstly, we convert a nonlinear problem into a …

A Comparison of Two Boundary Methods For Biharmonic Boundary Value Problems
<p>The purpose of this thesis is to solve biharmonic boundary value problems using two different boundary methods and compare their performances. The two boundary methods used are the method of fundamental solutions (MFS) and the method of approximate fundamental solutions (MAFS). The Delta-shaped …

Numerical solutions to Poisson's equation using radial basis functions
This thesis addresses the problem of obtaining solutions to Poisson's equation which is encountered in the applied sciences and engineering fields. Two separate methods are explained for obtaining particular solutions to this equation. The Method of Fundamental Solutions is then used to solve the …
