There are three node types:

• 1D fluid nodes. These are nodes satisfying at least one of the following conditions:
  • nodes belonging to 1D network elements (element labels starting with D)
  • reference nodes in *FILM cards of type forced convection (label: F*FC).
  • reference nodes in *DLOAD cards of type nodal pressure (label: P*NP).

• 3D fluid nodes. These are nodes belonging to 3D fluid elements (element labels starting with F)

• structural nodes. Any nodes not being 1D fluid nodes nor 3D fluid nodes.

It is not allowed to create equations between nodes of different types.
