“…Hamiltonian systems arise in applications where dissipative forces can be neglected [3], such as in conservative mechanical systems [6], astronomy [80], electrodynamics, molecular dynamics [1,2,7,8,64,78,84], plasma physics, and fluid dynamics [83]. Mechanical systems arise in many applications, e.g., in multibody dynamics of rigid and/or flexible bodies [36,69,70,71], in structural dynamics [14,15,17,20,37,38,39,40,55,56], in real-time vehicle-systems simulation [57], in aerospace applications [9], in biomechanics [48], and in robotics [43]. For mechanical systems a formulation eliminating the Coriolis forces and closely related to the Euler-Lagrange equations is presented.…”
