Re: NDSolve Repeated convergence test failure


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

that the equtaion is in normal form.

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