Looking To Element Quality In ANSYS Meshing(Illustrated Expression)

blank

ANSYS Mesher provides some kinds of tool to asses the obtained mesh elements in Mesh Metric options. You can asses you mesh structures that is created, and you can do some kinds of changes on this mesh structures according to these metrics. In this article we will explain and show;

  • What is ‘Element Quality’ in ANSYS Mesher?
  • How To See ‘Element Quality’ of a mesh structure in ANSYS Mesher?

Element Quality Mesh Metric In ANSYS Mesher

Select the ‘Element Quality’ from ‘Mesh Metric’

To see the ‘Element Quality’ of the obtained mesh structure, click on ‘Mesh’ tab as in green box then select the ‘Element Quality’ as shown by green arrow above from ‘Mesh Metric’ option inside the Statistics tab.

You can see the graph of ‘Element Quality’ mesh metric in ANSYS Mesher.

After selecting the ‘Element Quality’ option, you can see the minimum, maximum, average and the standard deviation of the element qualities of mesh elements as shown in red box above. Also there is a chart will be appeared to see the dispersion of element quality values in number of mesh elements for different mesh element types in ANSYS Mesher.

According to the ANSYS Meshing User’s Guide, ‘Element Quality’ of mesh structure calculated as below;

Element Quality calculation for 2D mesh elements in ANSYS Meshing.

As you can see from above equation, the ‘Element Quality’ is calculated like that for 2D elements individually. As you understand that the element quality depends on the area 2D mesh and the total edge length of 2D mesh structure in ANSYS Meshing.

Element Quality calculation for 3D mesh elements in ANSYS Meshing.

This element quality equation is valid for 3D meshing elements in ANSYS Meshing. The parameters are same for 2D and 3D mesh elements; volume and edge length. But the element quality equation changes drastically in ANSYS Meshing.

Value of ‘C’ according to the element type in element quality equations.

Also there is a parameter called ‘C’ in the element quality equations that changes according to the element types. Table above is showing the values of ‘C’ according to the given element types.

The general information about ‘Element Quality’ can be summarized as above. You can leave your questions and comments below about ‘Element Quality in ANSYS Meshing’.
