I was surprised (and pleased) to discover this, but it only works sometimes.

An attempt to impose a constraint inside the solution range fails.

It looks like you have circular definitions of v and y for the cases with errors.

I was wrong about the circular definitions...it works. You need to replace the independent variables in the odesolve call from t to x to agree with the rest of the problem. Both of the problems with errors work fine then.

Already answered.....hmmm?
