[deal.II] Re: Problems with hanging nodes and "distribute_local_to_global"

Heinrich, The way constraints are resolved in deal.II is as follows (related to *M. S. Shephard: Linear multipoint constraints applied via transformation as part of a direct stiffness assembly process. Int. J. Numer. Meth. Engrg., vol. 20 (1984), pp. 2107-2112.*): You have a linear system Ax=b
