An unfitted RBF-FD method in a least-squares setting for elliptic PDEs on complex geometries
Igor Tominec, Eva Breznik
Radial basis function generated finite difference (RBF-FD) methods for PDEs require a set of interpolation points which conform to the computational domain . One of the requirem…

A least squares radial basis function finite difference method with improved stability properties
Igor Tominec, Elisabeth Larsson, Alfa Heryudono
Localized collocation methods based on radial basis functions (RBFs) for elliptic problems appear to be non-robust in the presence of Neumann boundary conditions. In this paper we…
