Deleting nodes

Enter the Mesh module.
From the Object field in the context bar, select Part, and select a part from the list. This tool is available only for deleting orphan mesh nodes.
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.
In the dialog box, do the following:
1. In the Category field, select Node.
2. From the Method list, select Delete.
  If the Delete method is not shown, there are no orphan nodes in the selected part.
  Abaqus/CAE displays the existing nodes. In hidden and shaded mode only the visible nodes are displayed.
In the viewport, select the nodes to delete. You can ShiftClick on individual nodes to add them to your selection, or CtrlClick on selected nodes to remove them from your selection.
Tip: You can use the Selection toolbar to change the picking behavior. For more information, see Selecting objects within the viewport.”

If you would rather select from a list of existing node sets, do the following:
1. Click Sets on the right side of the prompt area.
  Abaqus/CAE displays the Region Selection dialog box containing a list of node sets that you have created.
2. Select the set of nodes that you want to delete, and click Continue.
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.

Abaqus/CAE displays the selected nodes and the elements associated with the selected nodes. (Both the nodes that you have selected and any elements associated with those nodes will be deleted.)
When you have finished selecting nodes to delete, click mouse button 2.
The elements associated with the selected nodes may also be associated with unselected nodes. If those unselected nodes would be left unassociated with any element after the nodes and associated elements are deleted, click Yes in the prompt area if you want Abaqus/CAE to delete those unselected nodes as well.
Tip: If you make a mistake while deleting nodes, click Undo in the Edit Mesh dialog box to undo the deletion. Abaqus/CAE restores the deleted node or nodes.
Repeat the previous steps as often as necessary to delete additional nodes.
When you have finished deleting nodes, click mouse button 2 or the cancel button in the prompt area to exit the procedure.
