Repair Mesh
Repair Mesh provides options to repair meshes. The parameters for repairing the mesh can be defined by clicking the Edit… button.
Repair Mesh is only available in MeshGeo, since it works on the mesh currently loaded in GeoDict. With ExportGeo-CAD, the meshes are saved directly and not loaded in the GeoDict user interface.
When a surface triangulation is loaded, select Repair Mesh and click Edit… to open the Repair Mesh dialog.
When all settings have been chosen, click Repair at the bottom of the MeshGeo section to create the mesh.
Do Edge Flip Optimization
With Do Edge Flip Optimization, folded edges in the mesh are analyzed and repaired by edge flipping. Folded edges are edges which meet in an angle close to 0°, which can cause problems when further working with the mesh.
Edge flipping refers to switching the end points of an edge in two adjacent triangles, which can help to avoid small angles. A simple example is shown in the screenshot below, where one of the triangles on the left has a very small angle. By flipping the edges, this problem is resolved.

Remove Duplicated Triangles
The duplicated triangles are checked and removed with Remove Duplicate Triangles. Two options are possible for the removing. One is Reduce to One Triangle, which leaves one instance of each set of duplicate triangles. The other one is Remove All, which removes all instances of each set of duplicate triangles.

Stitch adjacent meshes
With Stitch adjacent meshes, the meshes with overlapping boundary edges are merged. If Same material IDs only is checked, the merge is done only when the material IDs of the overlapping meshes are the same. Otherwise, the meshes with different material IDs are merged, too.

Manual Accuracy for Vertices
The option of Manual Accuracy for Vertices only takes effect when Remove Duplicate Triangles or Stitch adjacent meshes is used. It is to define a threshold to compensate for numerical errors in vertex coordinates. The mesh vertices that are no more than the given Epsilon / (µm) are considered equal.
