论一下有限差分法和有限体积法的区别与联系?
In finite difference (FD) methods, governing equations are discretized directly; while in finite volume (FV) methods, governing equations are integrated first over a control volume, then the obtained equations are discretized.
For FV, the governing equations should be in the conservation forms.
The detailed information could be obtained in Anderson';s CFD text. |
