We consider the application of the Method of Fundamental Solutions (MFS) to homogeneous force Stokes problems in 2 and 3 space dimensions. The choice of the main basis functions for the implementation of the MFS is justified by a new density result o

In this article, the inverse Cauchy problems in heat conduction under 3D functionally graded materials (FGMs) with heat source are solved by using a semi-analytical boundary collocation solver. In ...

In this paper we consider Trefftz methods which are based on functions defined by single layer or double layer potentials, integrals of the fundamental solution, or their normal derivative, on cracks. These functions are called cracklets, and satisfy

This paper addresses the application of a domain-type method of fundamental solutions (MFS-D) together with a Picard iteration scheme for solving nonlinear elliptic partial differential equations. A mathematical justification of the iterative process

Two meshfree methods are developed for the numerical solution of the non-homogeneous CauchyNavier equations of elastodynamics in an isotropic material. The two approaches differ upon the choice of the basis functions used for the approximation of the

We consider the inverse problem that consists in the determination of characteristic sources, in the modified and classical Helmholtz equations, based on external boundary measurements. We identify the location of the barycenter establishing a simple
