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 GRQUAD id number, all nodes associated with the referenced quad group are added to the node group.
- If item_ID is a negative GRQUAD id number, the nodes associated with the referenced quad group are deleted from the node group.
