Most often, ID numbers (IDs) for finite element nodes, elements, MPCs, and connectors are chosen and assigned automatically. The Renumber Action permits the IDs to be changed. This capability is useful to:
• Offset the IDs of a specific list of entities.
• Renumber the IDs of all existing entities within a specified range.
• Compact the IDs of an entity type sequentially from 1 to N.
IDs must be positive integers. Duplicate IDs are not permitted in the List of New IDs, or in the selected Entity List (old IDs). A Starting ID or a List of New IDs may be entered in the input databox. If a finite element entity outside the list of entities being renumbered is using the new ID, the renumber process will abort since each entity must have a unique ID.
The default is to renumber all the existing entities beginning with the minimum ID through the maximum ID consecutively starting with 1.
If only one ID is entered, it is assumed to be the starting ID. The entities will be renumbered consecutively beginning with the starting ID.
If more than one ID is entered, then there must be at least as many new IDs as there are valid old IDs. If there are fewer IDs in the List of New IDs than there are valid IDs in the selected Entity List, renumbering will not take place and a message will appear in the command line indicating exactly how many IDs are needed. The List of New IDs may not contain a #. However, the list may have more IDs than needed.
Important: | Try to estimate the number of IDs needed. A large number of unnecessary IDs will slow down the renumber process. |
The IDs in the selected Entity List may contain a #. The value of the maximum existing ID is automatically substituted for the #. There may be gaps of nonexisting entities in the list but there must be at least one valid entity ID in order for renumbering to take place.
An offset ID may be specified which will cause the new entity IDs to be equal to the old IDs plus the offset value.
A percent complete form shows the status of the renumber process. When renumbering is complete, a report appears in the command line indicating the number of entities renumbered and their new IDs. The renumber process may be halted at any time by pressing the Abort button and the old IDs will be restored.
