Ha, how often does it happen that you get to put a plug in for your own diploma thesis :-) In any case, if you can read German, this has the algorithm that you are looking for on p. 48/49: http://www.math.tamu.edu/~bangerth/publications/1998-thesis.pdf Thinking about it, step-28 also deals with these sorts of problems.
