The "Aspect Ratio" of a quad element in ICEM CFD is defined as the ratio of distanced between opposite vertices (shorter diagonal / longer diagonal). This definition imply that all regular rectangles (right-angled quadrilaterals with equal opposite sides) will have A.R. = 1 which is not correct.
Am I interpreting it wrongly? Thank you for your attention! Amod |

Yes, this is not correctly shown in the help A quick test reveals that it is calculating aspect ratio correctly and not how it is described in the help.
Thanks for catching and reporting this. I think the actual calculation may be the ratio between oposite midsides instead of diagonal corners... I have reported this to the doc team and they should fix it for the next release. I will try to post the correct doc here if I remember. |

We got the correct definition from Development and added it to the help. I created this image to help illustrate (we will put it into the help also).
Best regards (and thanks for catching this doc error), Simon |
