You can use this repair feature to remove short edges from the model.
Fault Finding Criteria
DesignModeler uses the length of the edge as the criteria to search for short edges in the model. An edge whose length lies between the minimum and maximum limit is determined to be a fault.
Methods Available
Vertex Connect: The two vertices of the short edge will be fused into one vertex and the edge will be deleted. The fused vertex will be at the mid point of the edge.
Edge Merge: The short edge will be merged with one or more adjacent edges. Ansys DesignModeler automatically suggests one adjacent edge for merging. You can change this selection if required. However, an edge needs to be specified for the operation to be successful.
Edge Delete: The short edge will be deleted using the Edge Delete method. Any gaps left behind by the delete operation are healed by growing adjacent edges.
Face Merge: The short edge will be fixed by merging a set of faces with the Face Merge method. If this method is chosen, you need to select the faces to merge. Note, while manually selecting faces for the face merge operation, you can select only those faces that use the vertices of the short edge or the short edge itself.
Note: The default value shown for Edge Merge method is "Automatic Selection" as Ansys DesignModeler suggests one adjacent edge for merge. But in case of Face Merge method, "0" is shown as you need to select the faces to merge. This method will not work for laminar edges, wire edges, and general body edges.
Example 88: Using Repair Edges Function
As an example of Repair Edges operation, consider the figure below. If you search for fault entities with default settings then four faults will be listed.
Fault 1: Ansys DesignModeler will suggest the Edge merge method to fix this fault. One of the adjacent edges of fault edge is suggested as merging edge. You can select both the adjacent edges for merging edge.
Fault 2: Ansys DesignModeler will suggest Vertex Connect method to fix this fault.
Fault 3: Ansys DesignModeler will suggest the Edge Merge method to fix this fault. If the desired result is a sharp corner, you can set the method to Edge Delete to get this result.
Fault 4: Ansys DesignModeler will suggest the Vertex Connect method to fix this fault. An alternate method to fix this fault is to use the Face Merge method and choose the four neighboring faces.
Results are shown in the figure below after Generate.
In case of Repair Edges, you are allowed to add faults manually. First, select an edge in the model and right click in the Graphics Window and choose "Add Group" from the context menu. After selecting this option, the edge will be added as a fault in the fault list.
