For statistical information about the mesh element quality, right-click the Mesh node () and select Statistics (). The Statistics window includes information about the minimum and average mesh element quality, a mesh element quality histogram, and more. The histogram shows the relative frequency of mesh elements with different quality values. Click the Statistics () button on the Mesh toolbar to print the total number of elements, the minimum element quality, and the average element quality in The Messages Window. Note that the skewness element quality measure is used for the values printed to the Messages window.

The Statistics window contains the following sections:

Define the geometric entities for which you want to display the statistics. Choose the level of the geometry from the Geometric entity level list:

From the Quality measure list, choose the mesh quality measure to use for the mesh statistics:

For more information about these mesh quality measures, see Mesh Element Quality.

In this section you find information on the status of the mesh: for example, if the mesh is empty, if the selection contains domains without mesh, or if an imported mesh contains second order elements. You can select the element type for which you want to see statistics from the Element type list. The default is to display statistics for All elements. The statistics includes the number of mesh elements of different types, such as tetrahedral elements and triangular elements. In the element statistics section below — for example, Domain element statistics — you find information about:

Not all these quantities are available for all options in the Element type list.

This section displays a histogram plot of the mesh element quality, using the selected mesh quality measure, for the specified element type and selection. The x-axis represents the element quality, and the y-axis represents the number of elements of similar quality. The absolute value of the mesh element quality is always between 0 and 1, where 0.0 represents a degenerated element and 1.0 represents the best possible element.

You can also create a histogram plot of the mesh element quality over the total area or volume of the elements by adding a Histogram plot to a 1D Plot Group and using a variable for a mesh quality measure as the expression.
