| Abstract: | The paper mainly discussed the characteristic of structured grids and unstructured grids and proposed three principles of grids choice.Take the rocket projectile exterior circumferential flow numerical simulation as the example,compared the memory possessive amount,the CPU time as well as the computation precision when used the structure grids and the non-structure grids.And the analysis results play a guide role in the grid choice of exterior circumferential flow of rocket projectile in numerical simulatio... |
