Re: NDSolve Repeated convergence test failure


Rob,

Thanks for your help!  This didn't work with Mathematica 4.2, but I just
tried it on Mathematica 5 (at school) and it worked!  Problem solved!

If the equation is changing order in the middle of the integration, it is
not possible to use an ordinary ODE method on it:  all of those assume
that the equtaion is in normal form.

However, the DAE solver appears to work just fine.
Try using the option SolveDelayed->True in NDSolve.
