Jan Stránský proposed the following answer:
Hi Yang,
what version of Yade do you use? I have a version from 2015-08-05 and there
this is fixed (but not tested very much)
cheers

To not update frequently is for sure causing most of the troubles. It resulted in wasting many developments in the last years. So, especially if you have a complex task like a coupling, I would suggest to update as often as possible.

Beside, I would be glad to discuss your project if you wish. You can register/write to yade-dev or email me personally, as you prefer.
