This capability means that a single undo removes your most recent change to
the mesh, a second undo removes the next most recent change, and so on.
Similarly, a single redo restores the most recently undone mesh change. The
graphic below shows that the Undo section of the
Edit Mesh dialog box includes short descriptions next to
the and buttons,
highlighting the mesh change that will be undone or redone if you click the
button.
When undo is disabled, a note appears in the description space instead, indicating that undo is disabled under Enabling undo and managing the cache. . To re-enable undo, seeAbaqus/CAE supports undo operations by recording a history of your mesh editing and bottom-up meshing operations in a memory cache. The allowable size of this cache, the size of your mesh, and the types of mesh editing you performed all determine how many levels of undo are permitted. For example, if your mesh has 100,000 elements and you define a maximum cache size of 0.5 million elements, Abaqus/CAE can provide at least five levels of undo. Operations such as creating or moving nodes do not require a large cache to undo.
