【已解決】網(wǎng)格的aspect ratio,有沒有明確的要求?
|
|
感覺幫助不夠具體,6.3.3. Grid Generation: Recommendations for grid generation are: Avoid high grid stretching ratios. Aspect ratios should not be larger than 20 to 50 in regions away from the boundary. Aspect ratios may be larger than that in unimportant regions. Aspect ratios may, and should, be larger than that in the boundary layers. For well resolved boundary layers at high Re numbers, the near-wall aspect ratios can be of the order of 10^5-10^6. 還有一段在11.5.1. General Considerations里: To avoid numerical errors, the aspect ratio of elements on the domain interface should be between 0.1:1 and 10:1 這個是只針對旋轉(zhuǎn)機械還是所有情況?
