Properties/Options/Descriptions

Display

Display Style: Enables you to change the display of the mesh in the graphical display window based on different criteria. The Display Style options include the following:

Use Geometry Setting (default): The display of the mesh in the Geometry window is based on the setting of the Display Style property of the Geometry object.

Mesh Metric information, which includes:

Shell Thickness (visible for surface/shell bodies only)

Element Quality

Aspect Ratio, based on either Triangle elements or Quadrilateral elements

Jacobian Ratio (MAPDL, Corner Nodes, or Gauss Points)

Warping Factor

Parallel Deviation

Maximum Corner Angle

Skewness

Orthogonal Quality

Characteristic Length (Autodyn)

Minimum Tri Angle

Maximum Tri Angle

Minimum Quad Angle

Maximum Quad Angle

Warping Angle

Tet Collapse

Aspect Ratio (Explicit)

Minimum Element Edge Length

Maximum Element Edge Length

Characteristic Length (LS-DYNA)

Deviation from Geometry: Display the deviation of the mesh nodes from the geometry.

Knockdown Factors: Visible only when your analysis includes an STL Support object and only once the STL Support object’s mesh has been generated. The option enables you to view the STL Support's elements with color-coded knockdown factors while you have the Mesh object selected.

Note: The use of Display Style to color mesh according to quality and the use of Mesh Metrics to view quality statistics are mutually exclusive. For example, when you are viewing Mesh Metrics, you cannot also view the mesh quality by color.
