Dear Jason and all,
Please correct me, if I’m wrong. According to my understanding, for every DLC the user assigns initial conditions (here mainly, Blade pitch and RPM ) to reduce the transient period of the simulations and to help the the controller find the stability earlier as possible.
For the same DLC (assume power production with wind gust) with different wind speeds, is it reasonable to assign different initial conditions, even though I’m assigning sufficient transient time? (lets say 100s) The simulation starts with considerable vibrations and in-time, around 90s, reaches reasonably stable position. But once the gust starts, the simulations behaves not as expected. Changing the initial conditions, changes this behavior.
Does the initial conditions have effect on the simulation, even after settling?
Any guidance is much appreciated.
Thanks and regards
