7 October 2012 11:26:27.746 AM SIMPLE_RKF45 FORTRAN77 version Simulate the behavior of three bodies which are constrained to lie in a plane, moving under the influence of gravity. Use RKF45 for the ODE integrator. SIMPLE_RKF45_RUN Simulate the planar three-body problem as an ODE system using RKF45 for the ODE integration. R8_RKFS - Fatal error! Invalid input. SIMPLE_RKF45_RUN - Warningc Output value of FLAG = 1 R8_RKFS - Fatal error! Integration cannot be continued. The user did not respond to the output value FLAG = 5, 6, 7, or 8.
