| Abstract: |
| Grid generation is very important to the numerical calculation of fluid flow. Many methods available can be used to achieve the target, but in this paper, only the method of Poisson equations was discussed. In addition to the traditional forms of source terms recommended by Thompson, a new one deduced by the authors was used in the calculation, and the comparison between the two forms gives several valuable conclusions. |
