NSNOD NLIN NSNFIX NVES NRICON NSPR NAKC
  • NSNOD: integer: Total number of supernodes

  • NLIN: integer, default: NSNOD-1: Number of lines

  • NSNFIX: integer, default: 1: Number of supernodes having one or more degrees of freedom that are fixed or prescribed

  • NVES: integer, default: 0: Number of support vessels

  • NRICON: integer, default: 0: Number of rigid supernode connections. Relevant for modelling of stiff connections between supernodes. The connection is described by specification of a master and a slave (dependent) node, see Rigid supernode connections

  • NSPR: integer, default: 0: Number of global springs

  • NAKC: integer, default: 0: Number of kill and choke lines. Relevant for modelling of tensioned risers only (Deprecated functionality)
