Abstract
This paper presents a mesh quality metric for hexahedral and wedge elements. A series of studies was carried out to relate the proposed metric with the solution errors. During the studies, the metric was also compared with the aspect ratio, the warping factor and the control number. The results show that the metric can be used to identify invalid as well as potential poor quality elements, which may cause larger solution errors.
