How to get the 6-DOF motion in openfoam_v1806?

Hello,everyone:
I am using openfoam_v1806 to run calculations related to floating bodies, and added anchor chain calculations to the floating bodies (this part uses the moody library on github). Due to the limitation of the anchor chain library, I can only use the rigidbodymotion solver instead of the sixdofrigidbodymotion solver to calculate, which leads to no center of mass in the openfoam log file, as shown below. I would like to know how to extract the six degrees of freedom motion of the floating body in this situation? Post-processing or what kind of functions are added to the controlDict? My files are attached.
Thanks in advance.I really need your help,
Brandon
