在ICEM里skewness和fluent里的skewness定义不一样。icem里skewness可接受范围是0.5-1,感觉在0.2以上就行。 在icem help里的定义: The skew is defined as one minus the ratio of the shorter diagonal over the longer diagonal. Thus, 0 is perfectly rectangular, and 1 represents maximum skewness. Eriksson Skewness This is an empirical criterion, obtained for a hexahedral element by dividing the volume of the closest parallelepiped by the product of its edges. It measures the shear of the parallelepiped closest to the current element using least squares approximation. The default range of values is 0–1. Generally acceptable elements have skewness ranging from 0.5 to 1. flunet中orthogonal quality最好在0.01以上。 如果有哪些不对的地方希望指正。 |
