How to access orientation tensor from top-level of solver?
 

I have a programming query and any help provided wil be gratefully received.

I am running a dynamic mesh case using OpenFOAM 2.0.1 and would like to access the orientation tensor (sixDoFRigidBodyMotion.orientation()) for the geometry, from the top-level of the solver.

Writing Foam::sixDoFRigidBodyMotion.orientation() does not work. This is because sixFoFRigidBodyDisplacement is a boundary condition (for the pointVectorField pointDisplacement). So effectively I am trying to access a function associated with a boundary condition.

This is not trivial to do, since the name of the patch and type of boundary condition are not known/constant.

If anyone can provide any assistance, or point me in the right direction to sort this out myself, I would be very grateful.

Kind Regards,

Clarence
