An Analysis of the Performance of Several Natural Neighbour-Based Galerkin Methods

Résumé

The Natural Element Method (NEM) has better accuracy than linear Finite Element Method when very distorted meshes are used. However the time needed to make the same calculation is higher in the meshless method than in FEM. Nevertheless, this computational cost includes, in the case of the meshless method, the user time employed in the mesh generation in the FEM. This article compares the cost in time using FEM and NEM with different shape functions and the accuracy of the obtained results.
