To merge edges:

From the main menu bar, select ToolsRepair.

ABAQUS/CAE displays the Geometry Repair Tools dialog box.

Tip:  You can also merge edges using the tool, located with the repair tools in the Part module toolbox. For a diagram of the repair tools in the toolbox, see “An overview of repair techniques,” Section 47.2.

From the dialog box, select Merge edges and click OK.

Select the edges that you want to merge. ABAQUS/CAE searches for all connected edges until it encounters a branch and selects all of the connected edges.

You can select the edges from the viewport or select an existing set containing the edges.

Note:  The default selection method is based on the selection method you most recently employed. To revert to the other method, click Select in Viewport or Sets on the right side of the prompt area.

You can use a combination of drag select, [Shift]+Click, [Ctrl]+Click, and the angle method to select more than one edge to merge. For more information, see “Selecting objects within the current viewport,” Section 6.2.

Tip:  If you are unable to select the desired edges, you can change the selection behavior by clicking the selection options tool in the prompt area. For more information, see “Using the selection options,” Section 6.3.

Click mouse button 2 to indicate that you have finished selecting edges.

Where possible, ABAQUS/CAE merges selected edges into single edges. ABAQUS/CAE displays an error message if no edges can be merged.

If you have finished repairing the part, you should check its validity by clicking mouse button 3 on the part in the Model Tree and selecting Update validity from the menu that appears.
