1 引言基于网格的方法(如有限体积法、有限元法等)是目前流动问题数值求解的主流方法.为了描述流动状态的演化过程并保证其计算精度,运用基于网格的数值方法求解流动问题往往需要不断地生成网格,而这种网格的生成通常需要耗费较多的人力和时间.无网格
The Element-Free Galerkin (EFG) method has got some applications in solid mechanics and materials mechanics. However, numerical solutions of EFG method for unsteady convection dominated problems are corrupted by spurious oscillations. Here, some stabilization methods are constructed for mitigating the spurious oscillation, which are Meshfree Streamline Upwind Petrov-Galerkin (MFSUPG), Meshfree Galerkin Least-Squares (MFGLS), Meshfree Sub-Grid Scale (MFSGS) and Meshfree Least-Squares (MFLS) method. Numerical...
