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¨C1. Generally acceptable elements have skewness ranging from 0.5 to 1. flunetÖÐorthogonal quality×îºÃÔÚ0.01ÒÔÉÏ¡£ Èç¹ûÓÐÄÄЩ²»¶ÔµÄµØ·½Ï£ÍûÖ¸Õý¡£ |
