Recent developments of meshless methods 93
residuals at all the collocation points. Both 1-D and 2-D examples are pre-
sented for examination of the convergence and performance of the present
PWLS method. Through the implementations of these numerical examples,
it is demonstrated that the PWLS method possesses the several advantages
listed below.
1. It is a truly meshless method since no mesh or integration is required.
2. Both the Dirichlet and Neumann boundary conditions can be easily
enforced.
3. The nal coefcient matrix is symmetric.
All advantages of the PWLS method ensure that it is a very good potential
meshless technique for a wide ...
