Question: pde solving example

I have this problem to my system:

sol := pdsolve(sys2, {bcs, ics}, numeric)
sol:-plot3d(u1(x, t), x = 2 .. 3.2, t = 100 .. 1000)
Error, (in pdsolve/numeric/plot3d) unable to compute solution for t>HFloat(0.0):
unable to store HFloat(undefined)+HFloat(undefined)*I when datatype=float[8]

It is 1 pde and 1 ode.

What can I do to solve it?
