> Differential equations may be split as a primary equation and several secondary equations. In some cases, the secondary equations may have an effect on he primary derivatives. This can be handled using the method computeDerivatives(double t, double[] primary, double[] primaryDot, double[] secondary, double[] secondaryDot) from the SecondaryEquations interface.
> However, when the secondary equations updateds the primaryDot array using this method, the update is ignored.

Next time when closing multiple issues, please consider using bulk edit.
You can suppress the e-mail messages when doing so.
