Hi, there! I have some general questions about deal.ii, and here is the background info concerning my question.
There are two functions u and v, defined over domain \Omega in 1D/2D/3D. We use deal.ii to solve for the numerical approximation of function u, using 1st degree polynomial for finite elements. That means that DOF on each cell is the same as values of function u at nodal points on each cell. In the mathematical model, we update the nodal values of function v using the nodal values of function u, pointwise, i.e., a nodal value of function v strictly depends on a nodal value of function u at the same nodal point. And that is the end of the process of solving for numerical approximations of functions u and v. After reading through many tutorial examples at deal.ii, I have not come across with answers to my following questions. They are, Is it possible to access nodal point values of a solution in deal.ii? And is it possible to revise nodal values of a solution pointwise? The tutorial examples show only how to access values of the solution at the quadrature points within each cell. Thanks for your insight on this question. -- 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.
