Hello,
I've tried defining both centreOfMass and centreOfRotation inside the dynamicMeshDict, as follows: Code:
... centreOfMass (0.4 0 0.1) centreOfRotation (-0.5 0 0.1) ... I see that from the sixDoFRigidBodyMotionState.C code that the solver will default to centreOfMass if the centreOfRotation isn't present: Code:
