Default Moment of Inertia in dynamicMeshDict for bodies out of global origin of the mesh

Hello,



I'm simulating a case of two degree of freedom with two similar circular cylinders (multiple patches) using pimpleDyMFoam solver.
I have some simple questions:
  1. How can I define dynamicMeshDict properties for each body (to calculate responses for each body)?
  2. Is the 'momentOfInertia' property in dynamicMeshDict defined in the world coordinate system? I mean, should I have to apply the parallel axis theorem if my bodies are not in the origin of the global system?
Thank you!
