A Hybrid Symplectic Integrator That Permits Close Encounters between Massive Bodies
Mixed-variable symplectic integrators exhibit no long-term accumulation of energy error , beyond that due to roundoo, and they are substantially faster than conventional N-body algorithms. This makes them the integrator of choice for many problems in Solar-System astronomy. However, in their original formulation, they become inaccurate whenever two bodies approach one another closely. This occu...
متن کاملClose encounters.
IN THE November issue of Nursing Management, airline pilot Chris Mann asked: 'Safety Culture? What safety culture?' ( Mann 2004 ). His paper summarises the training undertaken in the aviation industry particularly in relation to human factors, in recognition of their part in aviation safety. He posed the following questions of the NHS.
متن کاملAnomaly in Symplectic Integrator
Effective Liouville operators of the firstand the second-order symplectic integrators are obtained for the one-dimensional harmonic-oscillator system. The operators are defined only when the time step is less than two. Absolute values of the coordinate and the momentum monotonically increase for large time steps. PACS numbers: 05.10.-a, 02.10.Hh
متن کاملA minimal-variable symplectic integrator on spheres
We construct a symplectic, globally defined, minimal-variable, equivariant integrator on products of 2-spheres. Examples of corresponding Hamiltonian systems, called spin systems, include the reduced free rigid body, the motion of point vortices on a sphere, and the classical Heisenberg spin chain, a spatial discretisation of the Landau–Lifshitz equation. The existence of such an integrator is ...
متن کاملA Symplectic Integrator for Riemannian Manifolds l
There exist a number of mechanical systems having configuration and phase spaces that are differentiable manifolds which are not open subsets of Euclidean space. The spherical pendulum, which has configuration space the 2-sphere, and a single rigid body, with configuration space the Lie group SO(3), are two common examples. Integration algorithms, on the other hand, are usually set in the Eucli...
