Comments
- A node group is a set of nodes. It can
be defined explicitly by a list of:
- nodes
- entering a first and last node ID range which defines the group
- submodels (all nodes belonging to the listed submodel are included)
- submodels (all nodes defined by /NODE or /CNODE in the listed submodel are included)
- subsets or parts (all nodes belonging to the listed subset/part are included)
- property sets or materials (all nodes belonging to an element having those Property Type's/MID's are included)
- groups of nodes
- element groups (all nodes connected to those elements are included)
- a box (all nodes within a defined box are included)
- an unsorted node list: same as list of nodes, but the nodes are stored in the order of input not sorted numerically as with other options (only needed in /INTER/TYPE8 and /XELEM option).
- 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.
