You should test your code step by step, figuring out exactly where the error occurs. And then propose a technical and accurate question here. Time is expensive, and the developers offer their kind help to us, then we should respect their time and help. 在 2016年12月2日星期五

Dear Jean, I know that this website is not the code reviewer. I want to apply Neumann boundary condition on the curved side of my domain. It should be note that the domain is symmetry. I have considered half of a circle. It would be very kind of you if you let me know whether it is applied

Dear all, When I answer posts on the forum I try my best to add links to relevant portions of the documentation. I tend to choose (when I remember to do so) those from the developer page because I anticipate that these links would exist in perpetuity as we move to version 9 and beyond. As

Dear All, I want to apply non-zero neumann boundary condition on the curved domain of half of the circle. The way that I define my geometry, the boundary id and apply the Neumann B.C is written as follow: *Defining boundary id for different sections of domain (half_hyper_ball):* const

Dear Giulia, Judging by the lack of reply it seems that no-one knows of (or has implemented) an open-source library to specifically do model order reduction with deal.II. However, at least one of my colleagues uses deal.II to perform ROM via proper orthogonal decomposition, so deal.II
