Nodes are the most basic finite element entity. A node represents a physical position on the structure being modeled.

A node is used by an element entity to define the location and shape of that element. It is also used as temporary input to create geometry entities.

A node may contain a pointer to other geometric entities and can be associated directly to them.

Nodes are considered to be used if they are referenced in the definition of an element, system, vector, group, load, equation, or are referenced by any card image on any HyperWorks CFD entity. Unused nodes and any loads that are attached to unused nodes are automatically deleted.

Nodes cannot be organized into components. Nodes can also be organized into HyperWorks CFD include files, which defines the solver include file they will be exported to.
