Odesolve and boundary problem

[ValeryOchkov]

Can we use Odesolve for boundary problem.

I think for one ode can, but for 2, 3...See please the attach.

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?

Thanks, Harvey.

It was my error.

It is my odesolve (the temperature field in circular wall at static condition):
