| Abstract: |
| Numerical simulation is very easy to produce false diffusion for convection-domainated problem, Streamline upwind Petrov-Galerkin method(SUPG)is applied in MLPG (Meshless Local Petrov-Galerkin) method to lessen the influence of the convection term. Two cases that have benchmark solutions(rotate flow problem and Brezzi problem) are used to validate the accuracy and efficiency of the present method. The results show that the method can effectively overcome the influence of false diffusion; and compared with other upwind scheme in the literature, the method have very good stability and computational precise. |
