# Maximum Corner Angle Mesh Metric In ANSYS Meshing(Illustrated Expression)

Mesh metrics are frequently used to asses the mesh structures in ANSYS meshing. There are some kinds of mesh metric options to asses the different features of mesh structures. One of these mesh metric in ANSYS meshing is ‘Maximum Corner Angle’. In this article we will explain;

- What is ‘Maximum Corner Angle’ in ANSYS Meshing?
- How the ‘Maximum Corner Angle’ mesh metric is applied in ANSYS?

### What Is ‘Maximum Corner Angle’ Mesh Metric In ANSYS?

To adjust the mesh metric to ‘Maximum Corner Angle’ in ANSYS Meshing, click on ‘Mesh’ section inside the red box above then select the ‘Maximum Corner Angle’ as shown by red arrow from pop up ‘Mesh Metric’ menu in the Statistics.

After selecting the ‘Mesh Metric’ as ‘Maximum Corner Angle’, you can see the minimum, maximum, average and standard deviation values of maximum corner angles of meshing elements. Also you can see the dispersion of various maximum corner angle values around the mesh elements as chart in ANSYS.

The logic of maximum corner angle for a mesh structure or mesh elements is very basic. It defines the biggest angle value inside the geometrical shape that is created as mesh structure in ANSYS. You can understand the logic with below examples that taken from ANSYS Meshing User’s Guide.

As you can see above that the prefect triangular meh structures can be achieved with maximum corner angle value of 60 degrees. When it approaches to the 180 degress, mesh quality and calculations get worse.

The same logic is valid for quadrilateral mesh elements in ANSYS. When the maximum corner angle is 90 degrees, best mesh performance can be achieved.

So the smaller maximum corner angle value is better for mesh structure in ANSYS. The logic of maximum corner angle mesh metric in ANSYS can be explained like above.
