Hello SIMPACK Users,

I'm trying to run a free decay test on the 5MW-Fixed wind turbine provided by SIMPACK in the tutorial courses. There is a feature on SIMPACK to apply an Initial condition to the structure markers, Hence I applied an initial translation of 1 m in the x-direction and then ran a time integration of 120s. The free decay seems to be fine in the x-direction. Although there seems to be an initial displacement in the y-axis also. Please check the graphs below. I want to eliminate the initial displacement in the y direction. Is there any other way to apply a initial condition on SIMAPACK?

Appreciate your comments and help on this matter.
