Hi All, First of all, my question is very simple. But I can't find similar question.
Anyway, what I'm trying to do is to get error = |exact_solution - numerical_solution| (absolute value of two Deal.II Vector) and then plot this one using Visit. But I don't know how to change all elements of error(Deal.II Vector) to absolute values. Actually it seems that I can do this by solving (pi_i, pi_j) (error_j)=(pi_i,std::abs(exact_solution_i - numerical_solution_i)) (i.e. solving linear system) But, I wonder if there is more simple way to do that... Thank you.
