Integration Comparison Tests

A set of integration comparison tests were performed to test the application of various integrator and equation of motion combinations to different force model configurations. For each case force model configuration, a reference trajectory was generated at a 10 second time step using the Runge-Kutta-Fehlberg 7/8 integrator with relative error control set at 1.0e-13. Trajectories generated with other integrator and equation of motion combinations were compared to these reference trajectories and the results tabulated in the sample file. All differences are the maximum positional differences during the integration time span and are given in meters. These tables are not meant to be a definitive guide to integrator selection, but may be used to assist in that process.
