Abstract
Meshless methods are new numerical simulation methods. Meshless methods are based on a simple set of nodes that has to be optimized to obtain a good convergence of the approximation. For these reasons, in this paper, we have developed a new procedure in order to generate the initial set of nodes. This approach does not rely on any existing meshing technique, such as Delaunay or advancing front. It is based on a map density of nodes and a regularization procedure.
