[dune-pdelab] Initial conditions for instationary problems

[conf86 at web.de]

Hi,

I have another question regarding the dune-course examples.
I'm trying to figure out where exactly the initial conditions for t=t_0 are set in example03. I see that in example03_Q1.hh there is a function calling the initial condition, but I don't really see the source.
Or is it not set at all and 0 by default for this example? If so, is there an example-code how to set it?

Thank you in advance
