- Figure 1 – SpWeld Interface
Purpose:
This interface is used for showing, creating, modifying, and deleting *CONSTRAINED_SPOTWELD cards in LS-DYNA.
Controls:
Show – Show existing *CONSTRAINED_SPOTWELD entities
Modify – Modifying *CONSTRAINED_SPOTWELD values- Create – Create new *CONSTRAINED_SPOTWELD entities
- Delete – Delete *CONSTRAINED_SPOTWELD
