Comments
- Node groups are used to define secondary nodes of rigid walls, interfaces, rigid bodies or nodes to which a load is applied, like a concentrated load or a fixed velocity.
- If item_ID is a positive GRSHEL id number, all nodes associated with the referenced 4-node shell group are added to the node group.
- If item_ID is a negative GRSHEL id number, the nodes associated with the referenced 4-node shell group are deleted from the node group.
