Thank you for your answer. I am not sure if I fully understand your suggestion. Do you mean something like that:
Vector<*double*> vecSol; std::cout << "Solution at (0.2,0.2): "<< VectorTools::point_value(dof_handler, solution,Point<2>(0.2, 0.2),vecSol)<< std::endl; I still get some errors. Is there not any way to get for example the real part of *solution* easily and use it directly on the point_value as in step-3?
