If we modify the way ConstraintMatrix operates, we could work around this though: 1. Without rescaling those equations (as we do inside ConstraintMatrix right now) the spurious EV would all be equal to 1 and so ignoring them is easier. 2. One could also zero out the constrained rows after the fact. 3. Did we rip out the support for removing the constrained entries from the matrix completely? -- Timo Heister http://www.math.clemson.edu/~heister/ -- 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.
