I don't think there is anything like that in SymPy. It looks like you are expecting to solve a Cauchy initial value problem for partial differential equations. By the Cauchy-Kowalevski theorem, <https://en.wikipedia.org/wiki/Cauchy%E2%80%93Kowalevski_theorem>that is possible for equations with analytic coefficients. For the algorithm, you should look into the proof of the theorem.
