madique is on a distinguished road

I'm trying to simulate an oscillating system with translation and rotation and have been using dynamicBodyFvMesh to take care of the kinematics; however the simulation becomes unstable if the rotation amplitude is >30 degrees. I've heard that the problem may lie in the motion solver that I was using and have read that the SBR stress solver would be a better alternative for these rotation amplitudes. I would like to continue using dynamicBodyFvMesh (because it's easy to define the kinematics as frequencies and amplitudes); but how can I select the SBR stress solver instead of using the laplace face decomposition solver?
