In this work, an adaptive and efficient basis function is presented by which the Schrodinger equation can be solved using meshless method in an accurate and fast approach. The base of this achievement is the quantum wave packet. The proposed basis function reduces time consumption of the meshless method, approximately to half. Also, it inherits the fundamental properties of wave packets. Theref...
A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...
It is widely acknowledged that 3-D mesh generation remains one of the most man-hours consuming techniques within computational mechanics. The problem of mesh generation is that the time remains unbounded, even using the most sophisticated mesh-generator. For a given distribution of points, it is possible to obtain a mesh very quickly, but it may require several iterations, including manual inte...
