In Response To 'Re: Re: NDSolve difference b/w ver 8 and ver 9'
If you want to take the time to
run your notebook under V8 and show all the intermediate values, don't "hide" intermediate results that are likely to be crucially important behind semicolons, and explain all the steps that you are taking to solve your problem and then save the notebook
and then repeat that exact process with that identical notebook under V9 and then save the notebook under a different name
and post both notebooks and point out the hopefully few key places where the results diverge and you really need them to be the same then someone might be able to compare those and focus on a much smaller problem and try to find a way to give you an answer.
