output power of wind turbine

It does not look like a converged result to me. You should discard the first, say 600 iterations so that the initial large fluctuations for cm does not affect the y-range in the plot. I do not know your domain, mesh, numerical scheme etc so that I can not give you any advice now.

hi
i,m simulating a wind turbine as seen in photos .i used tetra for all of the domain.and i have a small cylindrical domain around turbine which is set as moving frame.
solver and bc:
steady-prs based-SST K-w -velocity inlet-prs outlet-turbine as moving wall with 0 relative to adjacent cell zone.

looks interesting. Im new to CFD and really liking what it can do so far. Is there anyone that could help me with this issue?

Its really bugging me and im certain its super simple and an experienced user could probably solve it in 5 seconds.

All the best
