Sanity check: conservation of angular momentum problem (sprinkler rotation)

Hi,

I'm trying to perform a co-simulation (acusolve-motionsolve) to solve a sprinkler rotation problem similar to this, I've finished the set-up lunched the computation, with no errors, while waiting for the solution to converge, I want to make sure that the problem is properly set up since I do not have a strong background in CFD codes ( being more structural oriented ). I have doubts concerning the interpolated motion set up ( I just set it up based on intuition), so far the solver didn't mention any thing about mesh distortion.

*.inp and *.xml files are attached. initial conditions files *.nic are compressed in the *.zip.

thank you for your support in advance.

Best regards
