Hi Samir!

Which version of DOLFIN are you using?

If you are using the convection-diffusion module in the latest
version, just change in src/demo/solvers/convdiff/main.cpp to

class Convection : public Function
{
  real operator() (const Point& p, unsigned int i) const
  {
    if ( i == 0 )
      return p.y;
    else
      return 0.0;
  }
};

/Anders
