I think I've made this kind of point on the mailing list before: You make it sound like you tried something, but it didn't work even though it should have, and you just moved on and tried something else instead. That's rarely a good approach: If it *should* work, it should work. If it doesn't, it's indicative of a bug somewhere, and you should try to find and *understand* the bug, rather than just go a different route that might simply result in a different way of exposing this kind of bug. Trust me: There is great power in *understanding* why something doesn't work! In your case, you've chosen an alternative route that also happens to be vastly more inefficient :-) Best W. -- ------------------------------------------------------------------------ Wolfgang Bangerth email: [email protected] www: http://www.math.colostate.edu/~bangerth/ -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
