Hello,

Check if the filling of the AMMGs is correct.
Enable the coupling card one by one to check the behavior.

Also, on your coupling cards displayed, normally the master side is the PART representing your ALE domain and then the coupling between AMMG and the structure is handled by MCOUP.
I saw 2 different "master" so maybe this is the issue.

Best Regards,

Loïc
