*ROTOR

Data format:

One line with 11 parameters followed by one line per blade

INOD ITYP NBLAD NSTRUT IRODIR ISPEED CUTI CUTO IPOS ISHAFT NRIG
NB1 IDL_1_1 ... IDL_NSTRUT_1 IDRIG_1_1 IDRIG_NRIG_1
...
NB_ NBLAD IDL_1_NBLAD ... IDL_NSTRUT NBLAD 1 IDRIG_1_NBLAD & IDRIG_NRIG_NBLAD

Status :

Optional

Restriction :

Blades groups must be defined as well as the reference node for the rotor.

Purpose :

To define a rotor for a turbine. The information will be used by the aerodynamic solver if any. Also specific treatment is performed by the mechanical solver since all elements encompassed by the keyword are potentially undergoing large rotations.

Details :

Parameter Description
INOD Rotor node & rotor ID
ITYP 0 for HWAT and 1 for VWAT
NBLAD number of blades
NSTRUT number of lines (group) linked to a blade (usually for VAWT turbines)
IRODIR 0 for rclockwise rotation, 1 for anti-clockwise rotation
ISPEED 0 for constant, 1 for variable not used in the prototype version
CUTI cut-in wind speed not used in this version
CUTO cut-out wind speed not used in this version
IPOS 0 for upwind position, 1 for downwind
ISHAFT ID number of the LS shaft group (0 if none)
NRIG Number of Rigid Bodies per blade
NB_i ith blade
IDL_j_i jth strut of the ith blade
IDRIG_j_i jth rigibody of the ith blade

The blade numbering depends on the order of the blade ID list.
