| Comment | Dirichlet boundaries are detected and dropped on coarser levels. Isolated nodes are aggregated and not skipped any more. |
| (Dropping them would decrease convergence) |
Description
Currently the nodes are skipped on the coarser level. That means boundary values have no effect on the coarser level!
Either those nodes should appear in the coarse matrix or should be incorporated into the right hand side
