      sixDoFSolver: Run-time selectable solver (integrator) for sixDoFRigidBodyMotion · 95c4f934
      Henry Weller authored
      The built-in explicit symplectic integrator has been replaced by a
      general framework supporting run-time selectable integrators.  Currently
      the explicit symplectic, implicit Crank-Nicolson and implicit Newmark
      methods are provided, all of which are 2nd-order in time:

          Can only be used for explicit integration of the motion of the body,
          i.e. may only be called once per time-step, no outer-correctors may be
          applied.  For implicit integration with outer-correctors choose either
          CrankNicolson or Newmark schemes.
      
          Example specification in dynamicMeshDict:
