*WTTHRUST

Data format:

A single line with 3 values

ID_TURBINE IDTAB TRAMP

Purpose :

To load the turbine in static in a very simplified way

Details :

Parameter	Description
ID_TURBINE	Turbine identification number
IDTAB	ID number of a two columns table (defined by *TABLEMCOL)
TRAMP	Ramp time to transition from static to dynamic loadings in the dynamic calculations

Note

On the hub reference node of the turbine ID_TURBINE, the wind velocity is computed in static. A horizontal force is obtained by interpolation in the table IDTAB (defined with *TABLEMCOL). The table has two columns linking wind velocity to horizontal force. The force is applied in the wind direction. In dynamic, the force is computed based on the instanteaneous wind velocity multiplied by a factor which decrease linearly from a value of 1 at t=0s to a value of 0 at t=TRAMP.
