Comments

  1. 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.
  2. If item_ID is a positive MAT id number, all nodes associated with the referenced mat group are added to the node group.
  3. If item_ID is a negative MAT id number, the nodes associated with the referenced mat group are deleted from the node group.
