Greetings all !(adsbygoogle = window.adsbygoogle || []).push({});

This is my first post on the forum, so please kindly let me know if I am not asking a proper question or on a proper board.

I would like to use Runge-Kutta 8th order method (89) in a celestial mechanics / astrodynamics application, written in C++. Therefore I wonder if anyone knows a good library / implementation that is documented and free to use ? It is ok if it is written in C, as long as there aren't any compilation problems to be expected.

So far I have found this library. The code seems ok, but I haven't found any information on licensing.

Can you help me by revealing some of the alternatives you might know and would suit my problem ?

Thank you very much and kind regards,

T
