Initial condition and desired solution in Opt control of heat eq

But according to the demo: u=0for Ω×{0}u = 0 \quad \textrm{for } \Omega \times {0} i.e. u=0 at t=0. I don’t undertand how and where we set that in the code.

In the demo, for the first time step u(0)=u0, Which is
u0=Function(V). Dolfin default every function to have a zero value. To set another initial condition, you have to change u0.
