Add a Corner Refinement node (
) to decrease the element size at sharp corners. The node considers a vertex in 2D or an edge in 3D to be a sharp corner if the angle between the adjacent selected boundaries, with respect to the selected domain, is greater than a specified angle.

On the Mesh ribbon toolbar (Windows) from the Operations>Modify (
 ) menu, choose Size>Corner Refinement. |

From the Mesh contextual toolbar (Mac and Linux), from the Modify (

To add it as a global node, right-click a Mesh node and select Corner Refinement. To add it as a subnode to a Mesh Operations node, right-click an operation node and select Corner Refinement. See Global vs. Local Attribute Nodes.

Specify the domains for which the node determines if the specified corners are sharp. Choose the level of the geometry from the Geometric entity level list:
|
•
|
Choose Entire geometry to specify that the node should determine sharp corners with respect to all domains. The corner refinement also considers corners not adjacent to any domain.
|
|
•
|
Choose Domain to specify the domains for which you want to determine sharp corners. Choose Manual in the Selection list to select the domains in the Graphics window or choose All domains to select all domains.
|
To specify the boundaries, click the Active button to turn it ON and select the boundaries in the Graphics window for which the corner refinement should determine the sharp corners. When the boundary selection is Active, the Domain Selection section Active button is automatically turned OFF.
Use the Minimum angle between boundaries field to specify the minimum angle between a pair of adjacent boundaries in the boundary selection for the refinement factor to apply at the vertex in 2D and edge(s) in 3D between the two boundaries. If a boundary pair is adjacent to one domain on each side (interior boundary) the corner refinement determines the angle(s) on the side(s) corresponding to the specified domain(s).
Use the Element size scaling factor field to specify a refinement factor (<1) that scales the element size for the vertices in 2D and edges in 3D corresponding to the sharp corners.
