As we said in all articles about mesh metrics in ANSYS, we use mesh metrics generally to assess the mesh structure situations on various bases. Also, one of these mesh metrics to assess the mesh structure situation is Orthogonal Quality in ANSYS. In this article we will explain;
- What is ‘Orthogonal Quality’ in ANSYS Meshing metrics?
- How do we look at the ‘Orthogonal Quality’ in ANSYS?
What is Orthogonal Quality Mesh Metric in ANSYS?
Firstly, to adjust the mesh metric to ‘Orthogonal Quality’, click on the ‘Mesh’ tab as in the red box. And select the ‘Orthogonal Quality’ from the pop-up menu as shown by the green box in ANSYS® Meshing.
After that, you can see the minimum, maximum, average, and standard deviation values of the mesh structure that you created. Also, there is a graph that shows the dispersion of various orthogonal quality mesh metrics according to the number of elements.

Furthermore, orthogonal quality is computed with vector mechanics. The program makes calculations by using the face normal vector. The vector from the cell centroid to the centroid of each of the adjacent cells. And the vector from the cell centroid to each of the faces. It sounds complex. But what you need to know about ‘Orthogonal Quality’ is, that 0 is the worst and 1 is the best.
Also, we use orthogonal quality generally to assess the mesh shape quality as skewness of mesh structures. Orthogonal quality can be described as above in very basic terms.
Finally, leave your comments and questions about the orthogonal quality in ANSYS Meshing.
