From: wolf Improved: When eliminating nodes from a matrix using the New:ConstraintMatrix::condense
functions, the
diagonal entry was set to one. It is now set to an entry that more
resembles the size of the other diagonal entries, so that we don't run
into scaling problems for applications that have very large or small
domains.
