I noticed that the Ricci tensor used to compute the constraints was computed incorrectly, and fixed this.  I have tested the fix and I am confident that it is correct.  I should have realised that this would have an effect on the test suites!  Some test suites output these constraints, so now that the constraints are different, the tests fail.  On this commit, the only failures in this test are due to the constraint variables.  HOWEVER: the test run with the current ET fails also because of differences in the ADM variables, so there must be another problem as well.  I will continue investigating.


There were two more problems, which I have detailed in https://trac.einsteintoolkit.org/ticket/690 and https://trac.einsteintoolkit.org/ticket/691.  Once these three issues are fixed, I believe all the tests will pass again.  There is no problem with the code itself, just with the tests.
