Mesh Repair Wizard-Degenerate elements

Fix Degenerate Elements by moving or merging nodes.

The Mesh Repair Wizard fixes two types of degenerate elements:

• elements that have two or three nodes very close together, which is fixed by merging the nodes
• elements that have one node very close to an opposite edge, which is fixed by moving the node into the middle of the opposite edge.

You can select the default tolerance shown on the panel (based on the global edge length internally), or specify an alternate tolerance value.

Dialog element	Explanation
Tolerance	Specifies the minimum height for triangles that are too small for a good mesh. Triangles with a height smaller than the minimum value are removed, and the mesh is regenerated in the area surrounding the removed triangles. Default Uses the default value, which is based on the global edge length. Specify Enter a value that you think is more appropriate for the minimum height of the triangles.
Show diagnostics	Select this option to see where degenerate elements are in the mesh.
Fix	Fixes the degenerate elements automatically, if possible.
Close	Closes the Mesh Repair Wizard without making any changes.
Finish	Fixes all the errors and summarizes the changes in the summary page. Click Close to close the dialog, with all the changes saved.
