To swap the diagonal:

1. Enter the Mesh module and do one of the following:

   • From the Object field in the context bar, select Assembly.

   • From the Object field in the context bar, select Part and select a part from the list.

2. From the main menu bar, select MeshEdit.

   Abaqus/CAE displays the Edit Mesh dialog box.

   Tip:  You can also display the Edit Mesh dialog box using the tool, located at the bottom of the Mesh module toolbox.

3. In the dialog box, do the following:

   1. In the Category field, select Element.

   2. From the Method list, select Swap diagonal (tri).

4. Select the edge of the adjacent triangular elements to swap. You can select only a single edge.

   Abaqus/CAE highlights the selected edge and prompts you to confirm that you want to swap the selected edge.

5. Click Yes to swap the element edge.

   Abaqus/CAE prompts you to select the next element edge to swap.

   Tip:  If you make a mistake while swapping a diagonal, click Undo in the Edit Mesh dialog box to undo the change. Abaqus/CAE restores the original diagonal in the two adjacent elements.

6. When you have finished swapping diagonals, click mouse button 2 or the cancel button in the prompt area to exit the procedure.
