Viewing Overall Element Quality

You can view the overall quality of the elements in your finite element model representation and represent each quality category statistically by selected criteria.

The activation state in the Quality Criteria editor determines the available list of criteria.

This task shows you how to:

View Element Quality in a Table
View Element Quality in Charts by Criteria

View Element Quality in a Table

You can view a table displaying the number and percentage of good, poor, and bad elements, as well as the worst element and average element, relative to several quality criteria.

From the Check section of the action bar, click Quality Analysis

Tip: You can also right-click the mesh in the tree and select Analyze to analyze the mesh quality of a single mesh. Alternatively, you can select Quality Analysis from the context menu in the Mesh Part Manager.

The Quality Report panel appears and displays tabs containing information about the meshes in the finite element model representation.

Select the Quality tab.

The Quality tab displays the following information:

The number and percentage of good, poor, and bad elements relative to all the quality criteria.
The quality criteria scores for the worst element in the mesh and for the average element.

The current criteria file information.

Important: If you previously edited the quality criteria for imported criteria, such as Elfini Checks, the Quality Report prompts you to synchronize the current FEM with the initialization criteria stored in the database.

The total number of elements in the Global mesh.

Tip: To reframe the view of the model to an element of a specific quality and criterion, right-click the cell in the criterion row that corresponds to the Poor, Bad, or Worst column and select Reframe On.

View Element Quality in Charts by Criteria

You can view charts displaying the number or percentage of good, poor, and bad elements, relative to several quality criteria, such as aspect ratio or minimal angle.

The charts display bar graphs corresponding to your customized view. You can adjust the number of intervals in your analysis to obtain a narrow or wide range of data points for each bar of the graph.

From the Check section of the action bar, click Quality Analysis

Tip: You can also right-click the mesh in thetree and select Analyze to analyze the mesh quality of a single mesh. Alternatively, you can select Quality Analysis from the context menu in the Mesh Part Manager.

The Quality Report panel appears and displays tabs containing information about the meshes in the finite element model representation.

From the options at the bottom of the Quality panel, click Statistic Curves .
The Statistics Curves dialog box appears as a separate tab docked with the Quality Report. Optionally, you can drag and extract the Statistics Curves to any position in the work area.
Select the tab corresponding to the criterion you want to view as a chart.
For example, select Maximal angle to view a bar graph that shows the number of the elements with maximal angles of specific degrees.
Optional: Select Number of Intervals to change the number of intervals in the display.
The number of intervals influences how the bar chart displays the range of values. A smaller number of intervals produces fewer bars in the graph, with a wider range of values per bar. A larger number of intervals produces more bars in the graph, with a narrower range of values per bar.

Select the numerical format to display:

Option	Description
Number of elements	The bar graph expresses the values as the actual number of elements.
Percentage of elements	The bar graph expresses the values of elements as a percentage of the whole.

The Statistics Curves dialog box displays bar graphs for the selected number of intervals in separate tabs for each criteria. The graph shows the number or percentage of elements of a particular value and measurement (such as degrees, millimeters, or ratios). The graph also displays the number or percentage of elements above and below these values.
