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? >
Yes, of course, the elements of your solution vector correspond to degrees of freedoms which are nodal values in your case. You simply access them (both for read and write) via operator(). DoFTools::map_dofs_to_support_points ( https://www.dealii.org/current/doxygen/deal.II/namespaceDoFTools.html#a5514e4f59ea659f63953d62ca429eaff ) might be useful if you need to know the support point for a given degree of freedom. The tutorial examples show only how to access values of the solution at the > quadrature points within each cell. > https://github.com/dealii/dealii/wiki/Frequently-Asked-Questions#how-to-get-the-mapped-position-of-support-points-of-my-element might also be helpful.
