Question:Problem with PDE Numeric Solution: "... when datatype = float [8] ..."

Both the equation defining a PDE and its boundary conditions involve functions that are the result of the numerical resolution process of an ODE system.

The PDE solution is obtained. However, when I want to calculate the value of the solution at some point the following error message is displayed: "Error, (in solnproc) unable to compute solution for t>HFloat(1.8936825887327868e15): unable to store HFloat(undefined)+HFloat(undefined)*I when datatype=float[8]".

I tried to formulate the problem differently. However, the error appeared again.

Where am I going wrong?

I've attached the PDE.mw file to the conference. 

Thank you for your help.
