Hi, sage has gsl as one of the included packages, which is very good for numerical solution of differential equations. have a look at examples on the wikipage - http://wiki.sagemath.org/interact/diffeq 'Vector Field with Runga-Kutta-Fehlberg' by Schilly is one of my favorites. i hope it will help. Best wishes, Rajeev
