Hello, This might be a simple question but I am stuck.
I am solving a vector problem similar to step-8. I have a Vector<double> solution with u_x and u_y at each dof. I would like to have another Vector<double> magnitude which stores the magnitude \sqrt(u_x^2+u_y^2) at each dof. Now it is clear that solution has double the size of magnitude. I need to extract the values of the magnitude vector for my weak form within the assembly loop not for post-processing. Why do I need this? Well I don't actually want the magnitude exactly, but what I need is the maximum value of my magnitude when I iterate in time. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
