拉格朗日方法的主要优点是它的适应性，满足远场边界条件，没有网格生成问题，没有基于网格的数值扩散。因此，希望避免将任何类型的（固定的）欧拉网格类型结构强加到计算上以保持这些益处。因此，我们选择不检查这样的混合方法，涡incell和耦合拉格朗日，有限差分法。
The main advantages of the Lagrangian method are its adaptability, satisfaction of far-field boundary conditions, lack of grid-generation problems, and the absence of grid-based numerical diffusion. Therefore it is desirable to avoid imposing any type of (fixed) Eulerian-grid type structure onto the calculation to preserve these benefits. Hence we have chosen not to examine such hybrid approaches as the vortex-incell and coupled Lagrangian, finite-difference methods.
