- now a more efficient boundary prolongation works correctly both for the uni- and multiprocessor runs; - the only difference now, however, since we are using a constant interpolation for the prolongation, is that the criterion for the refinement does not oscilate so much, but keeps the block at higher level until the fields are completely smooth; thus, the possibility of using linear interpolation should be reinvestigated; - the implemented method removes the necessity of repeating the prolongated boundary update twice;
