The Free Edges Diagnostic is used to find free edges in the mesh.
In the Free Edge Diagnostic text report, the following statistics are reported:
- Free Edges
- The number of element edges in the mesh that are not shared with other elements. If there are any free edges in a Dual Domain or 3D mesh, you must correct them before running an analysis. A Midplane mesh must have free edges at the outer edges of the model.
- Manifold Edges
- The number of manifold edges in the mesh. Properly connected elements have manifold edges. In a Dual Domain or 3D mesh, only manifold edges are correct.
- Non-Manifold edges
- The number of non-manifold edges in the mesh. If there are any non-manifold edges in any mesh, you must correct them before running an analysis.
A: Free Edges, B: Manifold Edges, C: Non-Manifold Edges
To fix a free edge problem, use appropriate tools from the Mesh Repair panel: (). For example, depending on the specific problem, Global Merge, Merge Nodes, Move Nodes, or Remesh Area may help.
