*WTHUB

Data format:

A single line with 2 values, as follows:

IDWT IDTAB

Status :

Optional

Purpose :

To specify a prescribed rotation velocity to a wind turbine.

Details :

Parameter	Description
IDWT	Wind turbine identification number
IDTAB	Table identification number

The table is defined by

*TABLEMCOL
ID NBL NMC
T_1 VEL_1
T_2 VEL_2
..
T_NBL VEL_NBL

Where IDTAB is the increment number of the table, NBL is the number of lines defined by the user and NBC=2. Then the data are entered. Note that the speed has to be provided in rad/s. The table provide the velocity as a function of time. Velocity is linearly interpolated between two time values of the table.

In combination with a simplified turbine model (NODECONT, NAME=TUSIM), IDTAB is not provided since the rotatonal velocity is computed rather than imposed.
