A new leapfrog integrator of rotational motion. The revised angular-momentum approach
Igor P. Omelyan
A new algorithm is introduced to integrate the equations of rotational motion. The algorithm is derived within a leapfrog framework and the quantities involved into the integration…

A new approach to the integration of rotational motion in systems with interacting rigid bodies
Igor P. Omelyan
A new approach is developed to integrate numerically the equations of motion for systems of interacting rigid polyatomic molecules. With the aid of a leapfrog framework, we directl…
